"But didn't you know it?" inquired Peggy Glenn, in her sweetest and most surprised tone.

Her voice was clear in the almost deserted dining-saloon, its lights winking against polished rosewood and its vast height wrenched with ghostly cracklings. The roof writhed in the fashion of tottering blocks; Morgan was not at all sure about that glass dome. To eat (or do nearly anything else) was a sporting performance in which you must look sharp for sudden rushes of the crockery from any corner of the table, from the snake-like dart of the water-glass to the majestic ground-swell of the gravy. Morgan felt like a nervous juggler. The dining-saloon would slowly surge up with an incredible balloon swell, climb higher, tilt, and plunge down from its height with a long-drawn roar of water that dislodged stewards from their pillars and made diners — clutching their chairs — feel a sudden dizziness in the pit of the stomach.

There were possibly a dozen people to stem a clattering avalanche of dishes and silver. In general, they were eating away grimly but cautiously, while a gallant orchestra attempted to play "The Student Prince." But none of this bothered Peggy Glenn. Suave in black velvet, with her black bobbed hair done into some sort of trick wave that lent a hoydenish air to her thin face, she sat at Captain Whistler's elbow and regarded him with naive surprise.

"But didn't you know it?" she repeated. "Of course Curtis can't help it, poor boy. It runs in the family, sort of. I mean, I shouldn't exactly call it insanity, of course… "

Morgan choked on a bit of fish and peered sideways at her. She appealed to him.

"I say, Hank, what was the name of that uncle of his Curt was telling us about? I mean the one who had the fits-and-gibbers or something in his sleep, or maybe it was claustrophobia, and used to give a terrific spring out of bed because he thought he was being strangled?"

Captain Whistler laid down his knife and fork. He had obviously been in an ill temper when he came to the table; but lie had concealed it under gruff amiability and absent-minded smiles. Wheeling round his chair he had announced that he must return to the bridge and could stay only for one course or two. Captain Whistler was stout and short of breath. He had protruding eyes of a pale brown colour, something like the hue of pickled onions, a ruddy face, and a large loose mouth which was always booming a professional and paternal "Ha-ha" to nervous old ladies. His gold braid blazed, and his short white hair stood up like the foam on a beer-glass.

Now he addressed Peggy with coy heartiness. "Come, come," he said in his best nursery manner, "and what is the little lady telling us now? Eh, my dear? Something about an accident to a friend of yours?"

"A dreadful accident," she assured him, looking round to make sure the dining-room would overhear. The only people at their own table were the captain, Dr. Kyle, Morgan, and herself; so she wanted to make sure. She described Warren's being picked up unconscious, with a wealth of graphic detail. "But, of course, poor boy, he isn't responsible for his actions when he gets into those fits… "

Captain Whistler looked concerned, and then rather alarmed. His fleshy face grew redder.

"Ah, hurrumph!" he said, clearing his throat. "Dear me! Dear me!" — it speaks much for the captain's social polish that he could sometimes force himself to say "Dear me!" — "Bad, bad, Miss Glenn! But there's nothing — ah — seriously wrong with him, is there?" He peered at her in gruff anxiety. "Is it maybe something in Dr. Kyle's line now?"

"Well, of course, I shouldn't like to say—"

"Have you known cases of the kind, Doctor?"

Kyle was not a man of many words. He was methodically disposing of grilled sole — a lean, long-faced figure with a bulging shirt-front, and traces of a thin smile had pulled down the furrows in his cheeks. He glanced at Peggy from under grizzled eyebrows, and then at Morgan. Morgan received the impression that he believed in Warren's lurid ailment about as much as he believed in the Loch Ness monster.

"Oh, yes," he replied in his heavy, meditative voice. "Not unknown. I've met it before." He looked hard at Peggy. "A mild case of legensis-pullibus, I should think. Patient'll recover."

In a harassed way Captain Whistler wiped his mouth with his napkin.

"But — ah — why wasn't I told of this?" he demanded. "I'm master here, and it's my right to be told of things like this… "

"I did tell you, Captain!" Peggy protested indignantly. "I've been sitting here the whole time telling you; I told you three times over before you understood. I say, what is worrying you?"

"Eh?" said the captain, jumping a little. "Worrying me? Rubbish, my dear! Rubbish! Ha-ha!"

"I mean, I hope we're not going to hit an iceberg or anything. That would be dreadful!" She regarded him with wide hazel eyes. "And, you know, they do say the captain of the Gigantic was drunk the night they hit the whale, and—"

"I am not drunk, madam," said Captain Whistler, his voice taking on a slight roar. "And I am not worried either. Rubbish!"

She seemed to have an inspiration. "Then I know what it is, poor dear! Of course. You're worried about poor Lord Sturton and all those valuable emeralds he's got with him… " Commiseratingly she looked at the chair which a very sea-sick peer had not yet occupied on the voyage. "And I don't blame you. I say, Hank, just fancy. Suppose there were a notorious criminal aboard — just suppose it, I mean — and this criminal had decided to pinch Lord Sturton's jewels. Wouldn't it be thrilling? Only not for poor Captain Whistler, of course; because he'd be responsible, wouldn't he?"

Under the table Morgan administered an unmannerly kick towards the shins of his beaming partner. His hps framed "Easy on!" But undoubtedly a number of diners had pricked up their ears.

"My dear young lady," said the captain, in an agitated voice, "for Go — ah — please kindly get that nonsense out of your pretty little head. Ha-ha! You'll alarm my passengers, you know; and I can't have that, can I? ( Lower your voice, will you?) The idea's fantastic. Come, now!"

She was appealing. "Oh dear, have I said anything I shouldn't? I mean, I was only supposing, to sort of relieve the monotony; because it has been rather dull, you know, and there hasn't been anything really funny, dear Captain Whistler, since I saw you playing handball on the boat-deck. But if there were a notorious criminal on board, it would be exciting. And it might be anybody. It might be Hank. Or it might be Dr. Kyle — mightn't it?"

"Verra likely," agreed Dr. Kyle composedly, and went on dissecting fish.

"But if I did have anything on my mind," declared the captain, in heavy joviality, "it would be about your uncle, Miss Glenn. He's promised to give us a full-dress performance of his marionettes at the ship's concert. And that's to-morrow night, my dear. He mustn't be ill for that, you know. He and his assistant — ah — well, they're — they're improving, aren't they?" said the captain, his voice rising to a desperate bellow as he tried to divert her. "I have looked forward, I have hoped, I have waited for the — ah — pleasure, the supreme honour," yelled Captain Whistler, of being present at a performance. And now you really must excuse me. I mustn't forget my duties, even at the expense of your charming company. I must — er — go. Good night, my dear. Good night, gentlemen."

He rolled away. There was a silence. Of the diners left at roundabout tables, Morgan noticed swiftly, only three people glanced after him. There was the sharp-edged, bony, shock-haired face of Mr. Charles Woodcock, the commercial traveller, who peered out motionless with his soup-spoon poised above his mouth as though he were going to pose for a figure on a fountain. At another table some distance away Morgan saw a man and a woman— both thin and well-dressed, their pale faces looking curiously alike except that the woman wore a monocle and the man a floating blond moustache like a feather waving from his lip. They stared after the captain. Morgan did not know who they were, but he saw them every morning. They made endless circuits of the promenade-deck, in absolute silence walking rapidly, with their eyes fixed straight ahead. One morning, in dull fascination, Morgan had watched them make one hundred and sixty-four circuits without a word. At the hundred and sixty-fifth they had stopped; the man said, "Eh?" and the woman said, "Ah!" and then they both nodded and went inside. It had occurred to Morgan to speculate how their marital relations were conducted… Anyhow, they seemed to be interested in the movements of Captain Whistler.

"The captain," said Morgan, frowning, "seems to have something on his mind…";

"Verra likely," agreed Dr. Kyle composedly. "I'll have the tripe and onions, steward."

Peggy Glenn smiled at him. "But I say, Doctor, do you think there might be a mysterious master criminal aboard?"

"Why, I'll tell you," said the doctor, bending his head. His shrewd eyes were amused; under the ragged brows whisking upwards at the corners, and with the furrows deepening round his mouth, Morgan thought uncomfortably that he looked a little too much like Sherlock Holmes. "And I'll put in a word of warning gratis. You're a clever young lady, Miss Glenn. But don't pull Captain Whistler's leg too hard. He'd be a bad man to have on the wrong side of anybody. Please pass the salt."

The dining-saloon soared up on another swell, and tilted amid sour notes from the orchestra. "But, really," said Peggy, "I mean, it's perfectly true about poor old Curt… "

"Oh, ah!" said Dr. Kyle. "Was he sober?"

"Doctor," she told him, lowering her voice confidentially, "I hate to tell it, but he was terribly, terribly drunk, poor boy. I mean, it's all right to speak of these things to a medical man, isn't it? But I pitied him from the bottom of my heart, poor boy, when I saw…"

Morgan got her away from the table after a brief and telegraphic exchange of kicks. They navigated the big staircase and stood in a breezy, lurching hall upstairs while Morgan said things. But Peggy, her prim little face beaming, only chortled with pleasure. She said she must go to her cabin and get a wrap, if they were going to watch with the others; also that she ought to look in on her Uncle Jules.

"By the way," she said, doubtfully, "I don't suppose you'd care to be a Moorish warrior, would you?"

"Not particularly," said Morgan, with conviction. "Is this relevant to the issue?"

"All you'd have to do, you know, would be blacken your face and put on some gilt armour and shawls and things; and stand at one side of the stage with a spear while Uncle Jules speaks the prologue… I wonder if you're tall enough, though? I say, Captain Valvick would make a ripping Moorish warrior, wouldn't he?"

"Oh, unquestionably."

"You see, there have to be two extras, a French warrior and a Moor, who stand on either side of the stage for effect. The stage isn't high enough for them to be on it; they're outside, on a little platform… When the play begins they go backstage, and sometimes they help move the figures — the unimportant ones that have nothing to do. Only my uncle and Abdul (that's his assistant) move the chief figures; they're the only ones with speaking parts… I say, it would be simply awful if Uncle Jules can't play. There's a professor or somebody aboard who's written all kinds of articles about his art. Abdul's all right and he could take the main part in place of uncle. But I'm the only other one, and I couldn't very well say the men's lines, could I?"

They had gone down into a tangle of passages on D deck, and Peggy knocked at a door. In response to a spectral groan, she pushed the door open. The cabin was dark except for a faint light over the washstand. That scene— with the cabin twisting sideways, and rain slashing the porthole — gave Morgan a slight shiver. Two or three witless-looking dummies were sprawled against the bulkhead in a seated position, and swayed with the motion as though they were moving their heads in a horrible chorus. The straps and hooks for their wires rattled eerily; they were solid lumps about four and a half feet tall; they glittered with gilt armour, red cloaks, and gaudy jewelled accoutrements. Their faces, bearded formidably in dark wool, smirked from under spiked helmets. While they swayed, a powerful-looking man with a flattish dark face sat on the couch with another dummy across his knee. In the dim light he was mending the figures cloak with a long needle and blue thread. Occasionally he glanced towards the dark berth where something heavy was burrowing and groaning.

"Je meurs!" whispered a voice from the berth, dramatically. "Ah, mon Dieu, je meurs! Oooool Abdul, je t'implore…

Abdul shrugged, squinted at his needle, shrugged again, and spat on the floor. Peggy closed the door.

"He's no better," she said, unnecessarily, and they started back to the cabin where Warren was waiting. Morgan, in fact, was not eager for more than a glimpse into that cabin. Whether it was merely night and the rain in the middle of a shouting Atlantic, or merely that dull after-dinner feeling which is not dispelled on shipboard without bibulous hilarity, still he did not like the look of those smirking dummies. Moreover, such an irrelevant impression as that had given him another impression — of trouble ahead. There was no Q.E.D. about it, or even a rational subtlety. But he glanced round rather sharply when they reached the side passage that led to Warren's cabin.

It opened off a main corridor, and its short length contained two cabins on either side. Warren's was an end one on the left, beside a door opening out on C deck. It was dark, and the white-painted door was hooked open. Morgan knocked in the manner agreed on at the door beside it, and they slipped inside.

Only the light inside the lower berth was on. Warren sat gingerly on the edge of the berth. And he looked worried.

Morgan said sharply, but in a low voice, "Anything wrong?"

"Plenty," said the other. "Sit down and keep as quiet as you can. I think we've got a long time to wait, but you never can tell what this joker will be up to. Valvick's gone for some soda-water. And we're set now." He nodded towards the ventilator high in the wall, communicating with the next cabin. "If anybody goes in there, we can hear him in a second. Then we nab him. Moreover, I've got the hook on the door wedged so that, no matter how quiet he tries to be, he'll make a racket as loud as an alarm clock."

Warren paused, rubbing his jaw rather nervously and peering about the dim-lit state-room. He had discarded the towel round his head, but absorbent gauze and sticking-plaster along the back of the skull still made his dark hair stand up in a goblin-like way. The glow in the berth illumined one side of his face, and they could see a vein beating in his temple.

"Curt," said the girl, "what is wrong?"

"All hell, I'm afraid. Old Valvick went to see Captain Whistler before dinner… "

"Yes?"

"Well, I don't know how much in earnest you people were when we were sitting in there piling up theories about fancy crooks. But the impossible happened. We were right. There's a very badly wanted little joker aboard, and no joke about it. He's after old Sturton's emerald. And — he's a killer."

Morgan felt in the pit of his stomach an uneasy sensation which was partly the motion of the ship. He said:

"Are you serious, or is this—?"

"You bet I'm serious. So is Whistler. Valvick got the information from him, because Whistler badly needs advice. Old Valvick's story is pretty muddled; but that much is clear. Whistler wonders whether to keep it dark or broadcast the news to the ship. Valvick advised the latter: it's customary. But Whistler says this is a respectable boat, a family boat, and the rest of that stuff… "

Morgan whistled. Peggy went over and sat down beside Warren. She protested stoutly that it was nonsense and she didn't believe it.

"Who is he, Curt? What do they know about him?" she demanded.

"That's just it. Nobody seems to know, except that he's travelling under an alias. You remember, I told you this afternoon that when I was in the radio-room old Whistler seemed to be having a row with the wireless operator?… Well, that was it. He'd got a radiogram. Fortunately, Valvik had the sense to persuade Whistler to let him take a copy of it. Have a look."

From his inside pocket he took an envelope, on the back of which was sprawled in crooked handwriting:

Commander S.S. Queen Victoria, at sea. Suspect Man responsible for Stelly job in Washington and Mac-gee killing here sailed under alias your ship. Federal officer arriving to-night from Washington and will send fuller information. Look out for smooth customers and advise if any suspects.

Arnold, Commissioner N.Y.P.D.

"I don't know anything about this MacGee killing, whatever it is, in New York," Warren went on, "but I know a little about the Stelly business because it raised such a row and looked like magic. It was tied up with the British Embassy. Stelly seems to have been a pretty well-

known English jewel-cutter and appraiser……."

"Hold on!" said Morgan. "D'you mean that Bond Street fellow, the one who's always designing the necklaces for royalty and having pictures of his work in the newspapers?"

Warren grunted. "Probably. Because it seems he was staying in Washington, and the wife of the British ambassador asked him to reset or redesign a necklace for her. I don't know the details of it — nobody knows much about it. But he left the British Embassy with the necklace one night, as safe as you please, and about four hours later they found him somewhere out Connecticut Avenue way. He was sitting on the kerbstone with his back propped up against a street lamp, and the back of his head smashed in. He didn't die, but he'll be a paralysed moron for the rest of his life, and never speak a word. That seems to be a quaint habit of this joker. He doesn't exactly kill; but he has a knack of softening their heads ho that they're worse than dead…

"By the Lord!" said Warren, clenching and unclenching his hands, "I'm wondering whether that's what / nearly got in the other cabin, only the fellow missed his aim when the ship rolled."

There was a silence, made portentous by creaking bulkheads and the blustering roar outside.

"I say, Peggy," Morgan observed, thoughtfully, "you'd better get out of this, old girl. It isn't funny. Go up to the bar and entice some gullibles into a bridge game. If this basher comes along and tries to pinch the rest of the film, we'll let you know. Meantime—"

The girl said, with vehemence, "Bah! You can't scare mc. You are a cheerful lot, though. Why don't you start telling ghost stories? If you start off by being afraid of this chap—"

"Who's afraid of him?" shouted Warren. "Listen, Baby. I've got something to settle, I have. When I get at him—" Satirically he watched her jump a little when there was a knock at the door. Captain Valvick bearing two large siphons of soda-water, bent his head under the door and closed it behind him with a mysterious air.

Morgan always remembered the ensuing two hours (or possibly three) on account of the interminable game of Geography that was played to pass away the time. Captain Valvick — cheerfully twinkling, in no whit disturbed — insisted that they should turn out the light, hook the door partly open, and get enough light from the dim bulb in the passage. First he administered to each a hair-raising peg of whisky, which made them feel anew the excellence of the adventure; then he placed them in a weird circle on the floor, with the bottle in the middle like a camp fire; finally, he filled up the glasses again.

"Skoal!" said the captain, raising his glass in the dim light. "Ay tell you, diss iss de life. Coroosh! But ay got to feel bad about Captain Whistler. Ho-ho! Dat poor old barnacle iss near crazy, you bet, on account of de crook which like to steal de jewellery. He iss afraid diss crook going to rob de English duke, and he try to persuade de duke to let him lock up de hemereld helephant in de captain's safe. But dat duke only give him de bird. He say, 'It be safer wit' me dan in your safe, or wit' de purser or anybody.' De captain say no. De duke say yes. De captain say no. De duke say yes… "

"Look here, you can omit the element of suspense," said Morgan, taking another drink. "What did they decide?"

"Ay dunno yust what dey decide. But ay got to feel bad about dat poor old barnacle. Come on, now; we play Geography."

This game was trying, but in many senses lively. As the whisky diminished, it led to long and bitter arguments between Warren and the captain. The latter, when stumped for a place-name, would always introduce some such place as Ymorgenickenburg or the River Skoof, in Norway. Warren would heatedly cast slurs on his veracity. Then the captain would say he had an aunt living there. As this was not considered prima facie evidence, he would embark on a long and complicated anecdote about the relative in question, with accounts of such other members of his family as happened to occur to him. Morgan's watch ticked on, and the stir about the boat gradually died away into a roaring night, as they heard about the captain's brother, August, his Cousin Ole, his niece Gretta, and his grandfather who was a beadle. Footsteps went by in the main corridor, but none of them turned into the side passage. It was growing stuffy in the cabin…

"I–I think he probably won't come," Peggy whispered, reverting to the subject for the first, time. There was an uneasy hopefulness in the way she said it.

"It's hotter than hell in here," muttered Warren. Glassware rattled faintly. "I'm tired of the game, anyhow. I think—"

"Listen!" said Morgan.

He had scrambled up and was holding to the side of the berth. They all felt it — a terrific draught blowing through the passage outside, rattling the hooks of the doors, and they heard the deeper tumult of the sea boiling more loudly. The door to D deck had been pushed open.

But it did not close. They were all standing up now, waiting to hear the swish and slam of that door as it closed against the compressed-air valve. Those doors were heavy; and in a wind you dodged inside quickly. But for an interminable time something seemed to be holding it partly open, while the draught whistled. The Queen Victoria rose, pitched, and went over in a long roll to starboard, but still the door stayed open. It was impossible to distinguish smaller noises above the crazy wickerwork creaking, but yet Morgan had an eerie sense that the door did not close because it could not; that there was something caught there, trapped in a snare and in pain, between the black sea and warm security inside.

They heard a moan. A faint voice seemed to be muttering something, muttering and repeating thinly in the passage. "Warren!" they thought it said. And again, "Warren…." until it died off in pain.
