lowering the napkin and stuffing it indifferently back into his coat pocket. "He may have loved 'em, but he apparently didn't allow 'em in here. Not on a regular basis, anyway. What do you make of it, Watson?"
Although my eyes were slower than his, I was also looking around. The double windows were all locked with thumb-turns and small brass side-bolts. None of the panes had been broken. Most of the framed charts and the box of weather instruments were between these windows. The other two walls were filled with books. There was a small coal-stove but no fireplace; the murderer hadn't come down the chimney like Father Christmas, not unless he was narrow enough to fit through a stovepipe and clad in an asbestos suit, for the stove was still very warm.
The desk stood at one end of this long, narrow, well-lit room; the opposite end was a pleasantly bookish area, not quite a library, with two high-backed upholstered chairs and a coffee-table between them. On this table was a random stack of volumes. The floor was covered with a Turkish rug. If the murderer had come through a trap-door, I hadn't the slightest idea how he'd gotten back under that rug without disarranging it . . . and it was not disarranged, not in the slightest: the shadows of the coffee-table legs lay across it without even a hint of a ripple.
"Did you believe it, Watson?" Holmes asked, snapping me out of what was almost a hypnotic trance. Something . . . something about that coffee-table . . .
"Believe what, Holmes?"
"That all four of them simply walked out of the parlour, in four different directions, four minutes before the murder?"
"I don't know," I said faintly.
"I don't believe it; not for a mo—" He broke off. "Watson! Are you all right?"
"No," I said in a voice I could hardly hear myself. I collapsed into one of the library chairs. My heart was beating too fast. I couldn't seem to catch my breath. My head was pounding; my eyes seemed to have suddenly grown too large for their sockets. I could not take them from the shadows of the coffee-table legs upon the rug. "I am most . . . definitely not . . . all right."
At that moment Lestrade appeared in the study doorway. "If you've looked your fill, H—" He broke off. "What the devil's the matter with Watson?"
"I believe," said Holmes in a calm, measured voice, "that Watson has solved the case. Have you, Watson?"
I nodded my head. Not the entire case, perhaps, but most of it. I knew who; I knew how.
"Is it this way with you, Holmes?" I asked. "When you . . . see?"
"Yes," he said, "though I usually manage to keep my feet."
"Watson's solved the case?" Lestrade said impatiently. "Bah! Watson's offered a thousand solutions to a hundred cases before this, Holmes, as you very well know, and all of them wrong. It's his bête noire. Why, I remember just this last summer—"
"I know more about Watson than you ever shall," Holmes said, "and this time he has hit upon it. I know the look." He began to sneeze again; the cat with the missing ear had wandered into the room through the door which Lestrade had left open. It moved directly toward Holmes with an expression of what seemed to be affection on its ugly face.
"If this is how it is for you," I said, "I'll never envy you again, Holmes. My heart should burst."
"One becomes inured even to insight," Holmes said, with not the slightest trace of conceit in his voice. "Out with it, then . . . or shall we bring in the suspects, as in the last chapter of a detective novel?"
"No!" I cried in horror. I had seen none of them; I had no urge to. "Only I think I must show you how it was done. If you and Inspector Lestrade will only step out into the hall for a moment . . . "
The cat reached Holmes and jumped into his lap, purring like the most satisfied creature on earth.
Holmes exploded into a perfect fusillade of sneezes. The red patches on his face, which had begun to fade, burst out afresh. He pushed the cat away and stood up.
"Be quick, Watson, so we can leave this damned place," he said in a muffled voice, and left the room with his shoulders in an uncharacteristic hunch, his head down, and with not a single look back. Believe
