Littlehaven was a fishing village situated on the marshy alluviums where a small river emptied itself into the sea at the head of a creek, running about a mile inland. The village itself was old, with twisted streets smelling of seaweed and of tar. It had a small harbour, where the smacks rode at anchor, and over the beach were always to be found black nets, redolent of fish scales, spread out for mending. Westward along the coast, towards the mouth of the creek, a modern bungalow town had sprung up, for the place provided good boating and fishing, and in the season the sea was alive with small craft; and the one hotel, a gaunt structure towering above the one-storied houses, was so full that it could afford to charge extremely high prices for most inferior accommodation. Out of season half of it was shut up and the bungalows presented an equally deserted appearance. Most of them were owned by enterprising tradesmen who furnished them for the purpose of letting them at exorbitant rents for three months of the year and were content to allow them to stand empty for the remaining nine months.
Along the coast on the other side of the creek were a few better-built bungalows standing grandly apart. These were the privately owned houses, disdaining to rub shoulders with their humbler neighbours, even holding themselves discreetly aloof from each other. They boasted quite large gardens, and were served by a road from the town of Lowchester, some ten miles inland.
On the Littlehaven side of the creek the bungalows grew less and less pretentious till they petered outt altogether; at the creek mouth a few fishermen's cottages huddled together round a Martello tower.
When the Bentley tore through Littlehaven Mr. Amberley did not stop to inquire for the Vauxhall, but jolted over the cobbled streets till he met the coast road. This had a tarred surface, and the car, badly hampered by the cobbles, leaped forward again and ran beside a depressing asphalt sea-walk, with the beach and the moonlit sea beyond, and a row of red and white bungalows on the other side of it.
From the level-crossing onwards Amberley had met with bad luck. Once the road was up and the signals had been against him; he had lost time waiting for a horse and wagon to crawl slowly over the narrow causeway; once, in a town of some size, he had been held up at every crossing and still further detained by the efforts of a blandly unconcerned female to turn a large Humber in a narrow road. She blocked the way for several precious minutes, twice stopping her engine, and looked stonily indignant when Amberley put his thumb on his electric hooter and kept it there. The sergeant's heart jumped into his mouth when, long before the female had completed her turn, the Bentley glided forward, mounted the pavement and almost brushed past the other car still, as it were, spreadeagled across the path.
But in spite of this ruthless manoeuvre time had been lost, and glancing at his watch Amberley doubted whether he had lessened the distance between the Bentley and the Vauxhall.
The sergeant, when he saw the sea with the moonlight on the water, was moved to remark that it looked pretty. He got no answer. "Where are we going to, sir?" he inquired.
"There's a creek," Amberley replied briefly. "We're almost on to it. On the opposite side, set back about four or five hundred yards from the seacoast, there is a bungalow. That's where we're going."
"We are, are we?" said the sergeant. "I suppose we just drive across the creek. Or swim."
"We shall go across in a boat," replied Amberley.
"Well, I'd as soon have gone round by road, sir," said the sergeant. "I never was a good sailor, and I don't suppose I ever shall be. What's more, I haven't got any fancy to have you driving me about in a motorboat, and that's the truth. Besides," he added, as a thought struck him, "how are you going to come by a motorboat at this hour?"
"I've got one waiting."
The sergeant was beyond surprise. "The only wonder to me is you haven't got an aeroplane waiting," he said. "Pity you didn't think of that. How did you come to have this here boat?"
"I hired it. I've a man watching the bungalow from this side of the creek. He'll take us across. I daren't risk going round by road. Takes too long, though that's the way the Vauxhall went. There's a wooden landing-stage at the bottom of the bungalow garden."
"Know all about it, don't you, sir?"
"I ought to. I came down here this morning to investigate."
"Well, I'll be jiggered!" said the sergeant. "Whatever made you do that, sir? Did you find anything out?"
"I did. I found that a certain privately owned motorboat has been fetched from Morton's Yard, which we passed a little way back, and made fast to a mooringbuoy about a quarter of a mile up the creek. Not only has she recently been overhauled, but her tanks are full. I found that so interesting, Sergeant, that I'm paying a longshoreman who lives in one of the cottages this side of the creek to watch the boat and the bungalow and let me know what he sees."
The sergeant found that he could still feel surprise after all. He would very much have liked to ask why Mr. Amberley should suddenly dart off to Littlehaven unknown to anyone, and why the vicissitudes of a motorboat should interest him in the least, but he thought it unlikely that he would get a satisfactory answer just now. He merely said: "Well, sir, I'll say one thing for you; for one who ain't in the Force you're very thorough. Very thorough indeed, you are."
The road curved inland; the sergeant could see the sheen of water and knew that they must have reached the creek. The car was slowing down and stopped presently in front of a small cottage about five hundred yards from the coast. The sergeant, peering, could just see the dark line of the shore -on the other side of the creek, and something that might have been a house reared the night sky.
Amberley had opened the door of the car and was getting out when suddenly he checked and said sharply: "Listen!"
Through the stillness of the evening the throb of a motorboat's engines drifted over the water to their ears.
A figure came across the road towards the car and shouted to Amberley, who looked quickly round.
"Is that you, sir? Well, I never! I was just going to get off to telephone you, like you said I was to. Well, of all the coincidences!" He caught sight of the sergeant's helmet and added: 'Lumme, is that a bobby?"
"You come here and tell us what you seen, my man," commanded the sergeant sternly.
It struck him that under his tan Mr. Amberley was very pale. Amberley's eyes were fixed on the longshoreman's face. "Be quick; let me have it."
"Well, there's someone gorn off in the motorboat," said the man. "gorn off this very minute. Ah, and he 'ad something with 'im, wot he carried over 'is shoulder. Well, I thought to myself, taking your luggage with you, are you? It might ha' been a sack. Well, sir, "e come down to that there landing-stage and 'e chucks this 'ere sack, or whatnot, into the dinghy wot's been tied up to the jetty, like you saw when you was down 'ere; and 'e gets out 'is oars and off 'e rows up the creek, me follering this side unbeknownst, and 'e comes alongside 'is motorboat and gets aboard with the luggage. Well, I thought, wot might you be up to now? - me not being able to see clear-like. Then I seen wot it was 'e was so busy with. banged if 'e weren't hitching the dinghy on to the motorboat. Then 'e starts 'er up and off 'e goes, "eading for the sea, the dinghy bobbing be'ind 'im. And wot 'e wants to take it along for fair beats me."
It beat the sergeant too, but he did not say so. He was looking sympathetically at Amberley, whose hand, lying on the door of the car, had gripped till the knuckles shone white. The longshoreman's description had convinced the sergeant that Shirley Brown had been done to death already. He did not wonder that Mr. Amberley stood there as though he'd been turned to stone. He wished he could have thought of something kind to say, but only managed to murmur gruffly: "Fraid we're too late, sir."
Amberley's eyes turned towards him; behind their blankness his brain was working desperately. "The dinghy," he said. "The dinghy. That means something. God, why can't I think?" He smote his hand down on the car in an impotent gesture.
"I must say, I don't see it myself, sir," said the sergeant. "What did he want it for when he had the motorboat?"
"To come back in!" Amberley said. "What other reason? Think, man, think!"
The sergeant did his best. "I don't hardly know, sir. He wouldn't hardly send the - the body out to sea in it, would he? He'll throw… I should say, he'd be more likely to throw it over… Well, what I mean is…' He broke off in embarrassment and was startled to find Amberley staring at him with a dreadful look in his face.
"My God, no, it's not possible!" Amberley said in a queer, strained voice.
"Ullo!" said the longshoreman suddenly. "Engine's stopped."
Amberley's head jerked up. The chug of the motorboat, which had been growing fainter, had suddenly stopped altogether.
"Well 'e's a rum 'un if ever there was one!" said the longshoreman. "E can't 'ave got much beyond the mouth o' the creek. Wot's 'e want to stop for?"
Amberley gave a great start. He swung himself back into the car and switched on the engine. "Get out!" he snapped. "Get out, Sergeant. You, there - Peabody! Row the sergeant across the creek. You've got to get that man, Sergeant. Stand by that Vauxhall; he's coming back to it. God's teeth, will you get out?"
The sergeant found himself thrust into the road. The Bentley was already moving, but he ran beside it shouting: "Yes, but where are you going, sir?"
"After that motorboat," Amberley shouted back him. "She's alive, you fool!"
The next moment he was gone, leaving two amazed creatures to stare at one another.
The longshoreman spat reflectively. "E's touched. Thought so all along."
The sergeant collected his wits. "You'll soon see whether he's touched or not," he said. "Come on now; I've got to get across the creek to that landing-stage I've heard so much about. Look lively!"
Back along the shore road tore the Bentley. The needle of the speedometer crept up to fifty, to sixty, to seventy. The creek was just a mile from Littlehaven, and Amberley reached Littlehaven harbour in one minute a half and drew up beside one of the yards with a jerk that sent a shudder through the car.
There was a man in a blue jersey locking up. He looked round in mild surprise as Amberley sprang out of the car.
When it penetrated to his intelligence that the gentleman wanted to set out to sea at once in a motorboat he glanced instinctively round for protection. It seemed him that a lunatic had broken loose from some asylum.
"I'm not mad," Amberley said. "I'm acting for the police. Is there any boat here ready to start?"
One had to humour lunatics; the sailor had often heard that. "Oh yes, sir, there's a motorboat all ready," he said, edging away.
His arm was grasped urgently. "Listen to me!" Amberley said. "A man has set out in a boat from the creek. I must catch that boat. There's ten pounds for you if get me there in time."
The sailor hesitated, trying to loosen the grip on his arm. Ten pounds were ten pounds, but the gentleman was clearly insane.
"Do I look as though I were mad?" Amberley said fiercely. "Where's that fast boat you had moored here this morning?"
The sailor scanned him closely. "Lord love me, I believe you're the Lunnon gentleman what come down here today arsting questions!" he exclaimed.
"I am. For God's sake, man, hurry! Any boat that's ready to start, the faster the better."
"Are you a plain-clothes man, sir?" inquired the sailor, awed.
"Yes," said Amberley without hesitation.
"Well, there's Mr. Benson's racing motorboat, and she's half full, I know. He had her out today, but I don't know as how…"
"Ten pounds!" Amberley snapped.
"Right you are, sir, and you takes the blame!" said sailor, and let him into the yard.
The racing motorboat was moored some fifty yards out. The sailor, having taken the plunge, seemed to realise that the need for haste was desperate and led Amberley at a trot to the steps. In less than a minute both men were in the dinghy that was tied up there and the sailor had cast off and shipped the oars.
The motorboat was covered with a tarpaulin, which was quickly stripped off. The sailor climbed into the well and started the engine. "She's warm, sir," he said. "Lucky, ain't you?"
Amberley was at the wheel. "I hope so," he said curtly.
The boat forged ahead, threading her way between the craft moored in the harbour. The sailor, perceiving that his odd passenger knew how to steer, took heart and needed no urging, once clear of the harbour, to speed the boat up. White foam began to churn up under the bows, the engine took on a deeper note.
The sea looked silver in the moonlight, deserted. Amberley held a course to the south-west, steering for a point out at sea where he judged he would overhaul the slower boat. The minutes crept by; to Amberley they seemed like hours. The noise of the engine thundered in his ears; he made a sign to the other man to shut it down.
The sailor obeyed. The sudden silence was like a blanket for a moment. The boat glided on, began to roll. Then through the silence Amberley's ears caught the sound for which they were listening. In the distance another boat was ploughing out to sea. He put the wheel over and called to the sailor to start her up again. The boat cleaved forward in a slightly altered course.
Amberley held her on this course for another five minutes and again signed to the sailor to shut down the engine. This time the noise of the other boat sounded closer at hand.
"'There she is! Go on!" Amberley said.
As he restarted the engine the sailor wondered who could be in the boat they were pursuing, and wished he had asked the gentleman. It was quite impossible to be heard above the noise of the engine, so he had to content himself with all manner of speculations, none of them, he felt, really probable. He kept an eye cocked in Amberley's direction, ready for another signal. It came very soon.
This time no sound broke the silence. The sailor, puzzled, said: "Thought we must have been right on her, the course we was steering! What's happened?"
Amberley pulled his torch from his pocket and sent its powerful beam out across the sea, sweeping a circle. It lit up the water for about two hundred yards but showed nothing but the silver ripples.
"Quickly! Start her!" Amberley jerked out. "Half speed!"
The boat began to cruise about, the torch-beam describing an arc of light ahead. The sailor heard Amberley say in a strangled voice: "Too late - God, I'm too late!"
Going round in a circle. I believe he's a looney after all, thought the sailor. Then he saw Amberley wrench the wheel hard over, staring out to where a dark object just showed above the water.
"Get on!" Amberley rapped out. "She's sinking fast!"
"Good Lord!" ejaculated the sailor, unprepared for this. "Sinking?"
"Get on, damn you!"
The boat gathered speed. They could see the other clearly now; she was down by the stern, half submerged.
The racing boat bore down upon her. "Easy!" Amberley ordered, and began to put the wheel over to come alongside. "Stop!"
The noise of the engine died, the racer glided on gently for a few feet and rocked beside the foundered boat.
The well was half full of water; Amberley had thrown his torch down to have both hands free, but the moonlight showed him all he wanted to see. Up against the side of the boat a white face was lifted just clear of the water, a scarf tied round the lower half of it.
"My Gawd in 'eaven!" gasped the sailor. "It's a woman!"
Amberley leaned over and grasped Shirley. She was strangely heavy; bound and weighted, he guessed. He said: "It's all right, my poor child, it's all right, Shirley," and shot over his shoulder: "A knife, quickly!"
The sailor, hanging on to the boat-hook with one hand, fished a clasp-knife out of his pocket and held it out. Amberley opened it and bent over the side, feeling under the water in the well of the other boat. His hand touched something hard about Shirley's waist; he could feel the links of an iron chain and the cord that tied them, and slashed through. In another moment he had her in his arms and had laid her down in the well of his own boat. She was deathly pale, but her eyes were wide open, fixed almost incredulously on his face. Her wrists and ankles were lashed together tightly; long shudders were running through her.
Amberley undid the scarf and took the gag out of her mouth; then he pulled the flask out of his hip pocket and put it to her blue lips, holding her against his shoulder. "Drink it, Shirley! Yes, I'll undo you, but drink this first. Good girl! - Take her in to shore as quick as you can, you - what's-your-name?"
"Aye, aye, sir. Leave it to me," said the sailor. "If you'll just steer her dear of this bit o' wreckage… Thank you, Captain!" He took the wheel over from Amberley and set the boat's nose back to port.
Amberley knelt beside Shirley and cut the ropes that bound her. Her wrists were deeply scored by them, but a faint, indomitable smile quivered on her lips. "You - always - turn up," she said, through chattering teeth.
"Th — thanks!"
