«I never said anything about your keeping out of the public,» said Lord Peter, easily, sitting down on the staircase to thrash the matter out comfortably, «though I've no doubt pussyfoot's a good thing, on principle, if not exaggerated. The golden mean, Sugg, as Aristotle says, keeps you from bein' a golden ass. Ever been a golden ass, Sugg? I have. It would take a whole rose-garden to cure me, Sugg —

«I'm not going to stay any longer talking to you,» said the harassed Sugg, «it's bad enough — hullo, drat that telephone. Here, Cawthorn, go and see what it is, if that old catamaran will let you into the room. Shutting herself up there and screaming,» said the Inspector, «it's enough to make a man give up crime and take to hedging and ditching.»

The constable came back:

«It's from the Yard, sir,» he said, coughing apologetically, «the Chief says every facility is to be given to Lord Peter Wimsey, sir. Um!» He stood apart noncommittally, glazing his eyes.

«Five aces,» said Lord Peter, cheerfully. «The Chief's a dear friend of my mother's. No go, Sugg, it's no good buckin' you've got a full house. I'm goin' to make it a bit fuller.»

He walked in with his followers.

The body had been removed a few hours previously, and when the bathroom and the whole flat had been explored by the naked eye and the camera of the competent Bunter, it became evident that the real problem of the household was old Mrs. Thipps. Her son and servant had both been removed, and it appeared that they had no friends in town, beyond a few business acquaintances of Thipps's, whose very addresses the old lady did not know. The other flats in the building were occupied respectively by a family of seven, at present departed to winter abroad, an elderly Indian colonel of ferocious manners, who lived alone with an Indian man-servant, and a highly respectable family on the third floor, whom the disturbance over their heads had outraged to the last degree. The husband, indeed, when appealed to by Lord Peter, showed a little human weakness, but Mrs. Appledore, appearing suddenly in a warm dressing-gown, extricated him from the difficulties into which he was carelessly wandering.

«I am sorry,» she said, «I'm afraid we can't interfere in any way. This is a very unpleasant business, Mr. — I'm afraid I didn't catch your name, and we have always found it better not to be mixed up with the police. Of course, if the Thippses are innocent, and I am sure I hope they are, it is very unfortunate for them, but I must say that the circumstances seem to me most suspicious, and to Theophilus too, and I should not like to have it said that we had assisted murderers. We might even be supposed to be accessories. Of course you are young, Mr. — »

«This is Lord Peter Wimsey, my dear,» said Theophilus mildly.

She was unimpressed.

«Ah, yes,» she said, «I believe you are distantly related to my late cousin, the Bishop of Carisbrooke. Poor man! He was always being taken in by impostors; he died without ever learning any better. I imagine you take after him, Lord Peter.»

«I doubt it,» said Lord Peter. «So far as I know he is only a connection, though it's a wise child that knows its own father. I congratulate you, dear lady, on takin' after the other side of the family. You'll forgive my buttin' in upon you like this in the middle of the night, though, as you say, it's all in the family, and I'm sure I'm very much obliged to you, and for permittin' me to admire that awfully fetchin' thing you've got on. Now, don't you worry, Mr. Appledore. I'm thinkin' the best thing I can do is to trundle the old lady down to my mother and take her out of your way, otherwise you might be findin' your Christian feelin's gettin' the better of you some fine day, and there's nothin' like Christian feelin's for upsettin' a man's domestic comfort. Good-night, sir — good-night, dear lady — it's simply rippin' of you to let me drop in like this.»

«Well!» said Mrs. Appledore, as the door closed behind him.

And —

said Lord Peter, «and taught me to be bestially impertinent when I choose. Cat!»

Two a. m. saw Lord Peter Wimsey arrive in a friend's car at the Dower House, Denver Castle, in company with a deaf and aged lady and an antique portmanteau.

«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 Pea-green 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.»
