“That only makes a fresh puzzle. One can’t suppose the murderer left them in that obliging manner as a clue to his own identity.”

“We can hardly suppose that; I’m afraid this man possessed what most criminals lack—a sense of humour.”

“Rather macabre humour.”

“True. But a man who can afford to be humorous at all in such circumstances is a terrible fellow. I wonder what he did with the body between the murder and depositing it chez Thipps. Then there are more questions. How did he get it there? And why? Was it brought in at the door, as Sugg of our heart suggests? or through the window, as we think, on the not very adequate testimony of a smudge on the window-sill? Had the murderer accomplices? Is little Thipps really in it, or the girl? It don’t do to put the notion out of court merely because Sugg inclines to it. Even idiots occasionally speak the truth accidentally. If not, why was Thipps selected for such an abominable practical joke? Has anybody got a grudge against Thipps? Who are the people in the other flats? We must find out that. Does Thipps play the piano at midnight over their heads or damage the reputation of the staircase by bringing home dubiously respectable ladies? Are there unsuccessful architects thirsting for his blood? Damn it all, Parker, there must be a motive somewhere. Can’t have a crime without a motive, you know.”

“A madman—” suggested Parker, doubtfully.

“With a deuced lot of method in his madness. He hasn’t made a mistake—not one, unless leaving hairs in the corpse’s mouth can be called a mistake. Well, anyhow, it’s not Levy—you’re right there. I say, old thing, neither your man nor mine has left much clue to go upon, has he? And there don’t seem to be any motives knockin’ about, either. And we seem to be two suits of clothes short in last night’s work. Sir Reuben makes tracks without so much as a fig-leaf, and a mysterious individual turns up with a pince-nez, which is quite useless for purposes of decency. Dash it all! If only I had some good excuse for takin’ up this body case officially—”

The telephone bell rang. The silent Bunter, whom the other two had almost forgotten, padded across to it.

“It’s an elderly lady, my lord,” he said. “I think she’s deaf—I can’t make her hear anything, but she’s asking for your lordship.”

Lord Peter seized the receiver, and yelled into it a “Hullo!” that might have cracked the vulcanite. He listened for some minutes with an incredulous smile, which gradually broadened into a grin of delight. At length he screamed: “All right! all right!” several times, and rang off.

“By Jove!” he announced, beaming, “sportin’ old bird! It’s old Mrs. Thipps. Deaf as a post. Never used the ’phone before. But determined. Perfect Napoleon. The incomparable Sugg has made a discovery and arrested little Thipps. Old lady abandoned in the flat. Thipps’s last shriek to her: ‘Tell Lord Peter Wimsey.’ Old girl undaunted. Wrestles with telephone book. Wakes up the people at the exchange. Won’t take no for an answer (not bein’ able to hear it), gets through, says: ‘Will I do what I can?’ Says she would feel safe in the hands of a real gentleman. Oh, Parker, Parker! I could kiss her, I reely could, as Thipps says. I’ll write to her instead—no, hang it, Parker, we’ll go round. Bunter, get your infernal machine and the magnesium. I say, we’ll all go into partnership—pool the two cases and work ’em out together. You shall see my body tonight, Parker, and I’ll look for your wandering Jew tomorrow. I feel so happy, I shall explode. O Sugg, Sugg, how art thou suggified! Bunter, my shoes. I say, Parker, I suppose yours are rubber-soled. Not? Tut, tut, you mustn’t go out like that. We’ll lend you a pair. Gloves? Here. My stick, my torch, the lampblack, the forceps, knife, pill-boxes—all complete?”
