“It’s very nice to see you, dear,” said the Dowager Duchess, placidly. She was a small, plump woman, with perfectly white hair and exquisite hands. In feature she was as unlike her second son as she was like him in character; her black eyes twinkled cheerfully, and her manners and movements were marked with a neat and rapid decision. She wore a charming wrap from Liberty’s, and sat watching Lord Peter eat cold beef and cheese as though his arrival in such incongruous circumstances and company were the most ordinary event possible, which with him, indeed, it was.

“Have you got the old lady to bed?” asked Lord Peter.

“Oh, yes, dear. Such a striking old person, isn’t she? And very courageous. She tells me she has never been in a motor-car before. But she thinks you a very nice lad, dear—that careful of her, you remind her of her own son. Poor little Mr. Thipps—whatever made your friend the inspector think he could have murdered anybody?”

“My friend the inspector—no, no more, thank you, Mother—is determined to prove that the intrusive person in Thipps’s bath is Sir Reuben Levy, who disappeared mysteriously from his house last night. His line of reasoning is: We’ve lost a middle-aged gentleman without any clothes on in Park Lane; we’ve found a middle-aged gentleman without any clothes on in Battersea. Therefore they’re one and the same person, Q.E.D., and put little Thipps in quod.”

“You’re very elliptical, dear,” said the Duchess, mildly. “Why should Mr. Thipps be arrested even if they are the same?”

“Sugg must arrest somebody,” said Lord Peter, “but there is one odd little bit of evidence come out which goes a long way to support Sugg’s theory, only that I know it to be no go by the evidence of my own eyes. Last night at about 9.15 a young woman was strollin’ up the Battersea Park Road for purposes best known to herself, when she saw a gentleman in a fur coat and top-hat saunterin’ along under an umbrella, lookin’ at the names of all the streets. He looked a bit out of place, so, not bein’ a shy girl, you see, she walked up to him, and said: ‘Good-evening.’ ‘Can you tell me, please,’ says the mysterious stranger, ‘whether this street leads into Prince of Wales Road?’ She said it did, and further asked him in a jocular manner what he was doing with himself and all the rest of it, only she wasn’t altogether so explicit about that part of the conversation, because she was unburdenin’ her heart to Sugg, d’you see, and he’s paid by a grateful country to have very pure, high-minded ideals, what? Anyway, the old boy said he couldn’t attend to her just then as he had an appointment. ‘I’ve got to go and see a man, my dear,’ was how she said he put it, and he walked on up Alexandra Avenue towards Prince of Wales Road. She was starin’ after him, still rather surprised, when she was joined by a friend of hers, who said: ‘It’s no good wasting your time with him—that’s Levy—I knew him when I lived in the West End, and the girls used to call him Peagreen Incorruptible’—friend’s name suppressed, owing to implications of story, but girl vouches for what was said. She thought no more about it till the milkman brought news this morning of the excitement at Queen Caroline Mansions; then she went round, though not likin’ the police as a rule, and asked the man there whether the dead gentleman had a beard and glasses. Told he had glasses but no beard, she incautiously said: ‘Oh, then, it isn’t him,’ and the man said: ‘Isn’t who?’ and collared her. That’s her story. Sugg’s delighted, of course, and quodded Thipps on the strength of it.”

“Dear me,” said the Duchess, “I hope the poor girl won’t get into trouble.”

“Shouldn’t think so,” said Lord Peter. “Thipps is the one that’s going to get it in the neck. Besides, he’s done a silly thing. I got that out of Sugg, too, though he was sittin’ tight on the information. Seems Thipps got into a confusion about the train he took back from Manchester. Said first he got home at 10.30. Then they pumped Gladys Horrocks, who let out he wasn’t back till after 11.45. Then Thipps, bein’ asked to explain the discrepancy, stammers and bungles and says, first, that he missed the train. Then Sugg makes inquiries at St. Pancras and discovers that he left a bag in the cloakroom there at ten. Thipps, again asked to explain, stammers worse an’ says he walked about for a few hours—met a friend—can’t say who—didn’t meet a friend—can’t say what he did with his time—can’t explain why he didn’t go back for his bag—can’t say what time he did get in—can’t explain how he got a bruise on his forehead. In fact, can’t explain himself at all. Gladys Horrocks interrogated again. Says, this time, Thipps came in at 10.30. Then admits she didn’t hear him come in. Can’t say why she didn’t hear him come in. Can’t say why she said first of all that she did hear him. Bursts into tears. Contradicts herself. Everybody’s suspicion roused. Quod ’em both.”

“As you put it, dear,” said the Duchess, “it all sounds very confusing, and not quite respectable. Poor little Mr. Thipps would be terribly upset by anything that wasn’t respectable.”

“I wonder what he did with himself,” said Lord Peter thoughtfully. “I really don’t think he was committing a murder. Besides, I believe the fellow has been dead a day or two, though it don’t do to build too much on doctors’ evidence. It’s an entertainin’ little problem.”
