Wolfe’s reaction was perfectly natural. True, he had just got wonderful news, but also he had just learned that if he had stayed home he would have got it just the same in tomorrow morning’s mail, and that was hard to take standing up. He hates going outdoors and rarely does, and he would rather trust himself in a room alone with three or four mortal enemies than in a piece of machinery on wheels.

But he had been driven to the wall. Four people live in the old brownstone house on West 35th Street. First, him. Second, me, assistant everything from detective to doorbell answerer. Third, Fritz Brenner, cook and house manager. And fourth, Theodore Horstmann, tender and defender of the ten thousand orchids in the plant rooms on the roof. But that was the trouble: there was no longer a fourth. A telegram had come from Illinois that Theodore’s mother was critically ill and he must come at once, and he had taken the first train. Wolfe, instead of spending a pleasant four hours a day in the plant rooms pretending he was hard at it, had had to dig in and work like a dog. Fritz and I could help some, but we weren’t experts. Appeals were broadcast in every direction, especially after word came from Theodore that he couldn’t tell whether he would be back in six days or six months, and there were candidates for the job, but no one that Wolfe would trust with his rare and precious hybrids. He had already heard of this Andrew Krasicki, who had successfully crossed an Odontoglossum cirrhosum with an O. nobile veitchianum, and when he learned from Lewis Hewitt that Krasicki had worked for him for three years and was as good as they come, that settled it. He had to have Krasicki. He had written him; no answer. He had phoned, and had been brushed off. He had phoned again, and got no further. So, that wet December morning, tired and peevish and desperate, he had sent me to the garage for the car, and when I rolled up in front of the house there he was on the sidewalk, in his hat and overcoat and cane, grim and resolute, ready to do or die. Stanley making for Livingstone in the African jungle was nothing compared to Wolfe making for Krasicki in Westchester.

And here was Krasicki saying he had already written he would come! It was an awful anticlimax.

“I want to sit down,” Wolfe repeated firmly.

But he didn’t get to, not yet. Krasicki said sure, go on in and make himself at home, but he had just been starting for the greenhouse when we arrived and he would have to go. I put in to remark that maybe we’d better get back to town, to our own greenhouse, and start the day’s work. That reminded Wolfe that I was there, and he gave Krasicki and me each other’s names, and we shook hands. Then Krasicki said he had a Phalaenopsis Aphrodite in flower we might like to see.

Wolfe grunted. “Species? I have eight.”

“Oh, no.” It was easy to tell from Krasicki’s tone of horticultural snobbery, by no means new to me, that he really belonged. “Not species and not dayana. Sanderiana. Nineteen sprays.”

“Good heavens,” Wolfe said enviously. “I must see it.”

So we neither went in and sat down nor went back to our car, which was just as well, since in either case we would have been minus a replacement for Theodore. Krasicki led the way along the path by which we had come, but as we approached the house and outbuildings he took a fork to the left which skirted shrubs and perennial borders, now mostly bare but all neat. As we passed a young man in a rainbow shirt who was scattering peat moss on a border, he said, “You owe me a dime, Andy. No snow,” and Krasicki grinned and told him, “See my lawyer, Gus.”

The greenhouse, on the south side of the house, had been hidden from our view as we had driven in. Approaching it even on this surly December day, it stole the show from the mansion. With stone base walls to match the house, and curving glass, it was certainly high, wide, and handsome. At its outer extremity it ended in a one-story stone building with a slate roof, and the path Krasicki took led to that, and around to its door. The whole end wall was covered with ivy, and the door was fancy, stained oak slabs decorated with black iron, and on it was hanging a big framed placard, with red lettering so big you could read it from twenty paces:

DANGER

DO NOT ENTER

DOOR TO DEATH

I muttered something about a cheerful welcome. Wolfe cocked an eye at the sign and asked, “Cyanogas G?”

Krasicki, lifting the sign from its hook and putting a key in the hole, shook his head. “Ciphogene. That’s all right; the vents have been open for several hours. This sign’s a little poetic, but it was here when I came. I understand Mrs. Pitcairn painted it herself.”

Inside with them, I took a good sniff of the air. Ciphogene is the fumigant Wolfe uses in his plant rooms, and I knew how deadly it was, but there was only a faint trace to my nose, so I went on breathing. The inside of the stone building was the storage and workroom, and right away Wolfe started looking things over.

Andy Krasicki said politely but briskly, “If you’ll excuse me, I’m always behind a morning after fumigating...”

Wolfe, on his good behavior, followed him through the door into the greenhouse, and I went along.

“This is the cool room,” Krasicki told us. “Next is the warm room, and then, the one adjoining the house, the medium. I have to get some vents closed and put the automatic on.”

It was quite a show, no question about that, but I was so used to Wolfe’s arrangement, practically all orchids, that it seemed pretty messy. When we proceeded to the warm room there was a sight I really enjoyed: Wolfe’s face as he gazed at the P. Aphrodite sanderiana with its nineteen sprays. The admiration and the envy together made his eyes gleam as I had seldom seen them. As for the flower, it was new to me, and it was something special — rose, brown, purple, and yellow. The rose suffused the petals, and the brown, purple, and yellow were on the labellum.

“Is it yours?” Wolfe demanded.

Andy shrugged. “Mr. Pitcairn owns it.”

“I don’t care a hang who owns it. Who grew it?”

“I did. From a seed.”

Wolfe grunted. “Mr. Krasicki, I’d like to shake your hand.”

Andy permitted him to do so and then moved along to proceed through the door into the medium room, presumably to close more vents. After Wolfe had spent a few more minutes coveting the Phalaenopsis, we followed. This was another mess, everything from violet geraniums to a thing in a tub with eight million little white flowers, labeled Serissa foetida. I smelled it, got nothing, crushed one of the flowers with my fingers and smelled that, and then had no trouble understanding the foetida. My fingers had it good, so I went out to the sink in the workroom and washed with soap.

I got back to the medium room in time to hear Andy telling Wolfe that he had a curiosity he might like to see. “Of course,” Andy said, “you know Tïbouchina semidecandra, sometimes listed as Pleroma mecanthrum or Pleroma grandiflora.”

“Certainly,” Wolfe assented.

I bet he had never heard of it before. Andy went on. “Well, I’ve got a two-year plant here that I raised from a cutting, less than two feet high, and a branch has sported. The leaves are nearly round, not ovate, foveolate, and the petioles — wait till I show you — it’s resting now out of light—”

He had stepped to where a strip of green canvas hung from the whole length of a bench section, covering the space from the waist-high bench to the ground, and, squatting, he lifted the canvas by its free bottom edge and stuck his head and shoulders under the bench. Then he didn’t move. For too many seconds he didn’t move at all. Then he came back out, bumping his head on the concrete bench, straightened up to his full height, and stood as rigid as if he had been made of concrete himself, facing us, all his color gone and his eyes shut.

When he heard me move his eyes opened, and when he saw me reaching for the canvas he whispered to me, “Don’t look. No. Yes, you’d better look.”

I lifted the canvas and looked. After I had kept my head and shoulders under the bench about as long as Andy had, I backed out, not bumping my head, and told Wolfe, “It’s a dead woman.”

“She looks dead,” Andy whispered.

“Yeah,” I agreed, “she is dead. Dead and cooled off.”

“Confound it,” Wolfe growled.
