Mr. Parker was greatly relieved, if somewhat surprised, by the modesty of the lady’s demands, and, placing his foot on the door-scraper in an easy attitude, prepared to wait with patience. Before many minutes, however, the door was opened by a thin, middle-aged woman, with a sharp, sallow face and very vivacious manner. She wore a neat, dark coat and skirt, a high-necked blouse and a long gold neck-chain with a variety of small ornaments dangling from it at intervals, and her iron-grey hair was dressed under a net, in the style fashionable in the reign of the late King Edward.

“Oh, Lord Peter! How very nice to see you. Rather an early visit, but I’m sure you will excuse the sitting-room being a trifle in disorder. Do come in. The lists are quite ready for you. I finished them last night. In fact, I was just about to put on my hat and bring them round to you. I do hope you don’t think I have taken an unconscionable time, but there was a quite surprising number of entries. It is too good of you to trouble to call.”

“Not at all, Miss Climpson. This is my friend, Detective-Inspector Parker, whom I have mentioned to you.”

“How do you do, Mr. Parker—or ought I to say Inspector? Excuse me if I make mistakes—this is really the first time I have been in the hands of the police. I hope it’s not rude of me to say that. Please come up. A great many stairs, I am afraid, but I hope you do not mind. I do so like to be high up. The air is so much better, and you know, Mr. Parker, thanks to Lord Peter’s great kindness, I have such a beautiful, airy view, right over the houses. I think one can work so much better when one doesn’t feel cribbed, cabined and confined, as Hamlet says. Dear me! Mrs. Winbottle will leave the pail on the stairs, and always in that very dark corner. I am continually telling her about it. If you keep close to the banisters you will avoid it nicely. Only one more flight. Here we are. Please overlook the untidiness. I always think breakfast things look so ugly when one has finished with them—almost sordid, to use a nasty word for a nasty subject. What a pity that some of these clever people can’t invent self-cleaning and self-clearing plates, is it not? But please do sit down; I won’t keep you a moment. And I know, Lord Peter, that you will not hesitate to smoke. I do so enjoy the smell of your cigarettes—quite delicious—and you are so very good about extinguishing the ends.”

The little room was, as a matter of fact, most exquisitely neat, in spite of the crowded array of knick-knacks and photographs that adorned every available inch of space. The sole evidences of dissipation were an empty eggshell, a used cup and a crumby plate on a breakfast tray. Miss Climpson promptly subdued this riot by carrying the tray bodily on to the landing.

Mr. Parker, a little bewildered, lowered himself cautiously into a small arm-chair, embellished with a hard, fat little cushion which made it impossible to lean back. Lord Peter wriggled into the window-seat, lit a Sobriane and clasped his hands above his knees. Miss Climpson, seated upright at the table, gazed at him with a gratified air which was positively touching.

“I have gone very carefully into all these cases,” she began, taking up a thick wad of type-script. “I’m afraid, indeed, my notes are rather copious, but I trust the typist’s bill will not be considered too heavy. My handwriting is very clear, so I don’t think there can be any errors. Dear me! such sad stories some of these poor women had to tell me! But I have investigated most fully, with the kind assistance of the clergyman—a very nice man and so helpful—and I feel sure that in the majority of the cases your assistance will be well bestowed. If you would like to go through—”

“Not at the moment, Miss Climpson,” interrupted Lord Peter, hurriedly. “It’s all right, Charles—nothing whatever to do with Our Dumb Friends or supplying Flannel to Unmarried Mothers. I’ll tell you about it later. Just now, Miss Climpson, we want your help on something quite different.”

Miss Climpson produced a business-like notebook and sat at attention.

“The inquiry divides itself into two parts,” said Lord Peter. “The first part, I’m afraid, is rather dull. I want you (if you will be so good) to go down to Somerset House and search, or get them to search, through all the death-certificates for Hampshire in the month of November, 1925. I don’t know the town and I don’t know the name of the deceased. What you are looking for is the death-certificate of an old lady of 73; cause of death, cancer; immediate cause, heart failure; and the certificate will have been signed by two doctors, one of whom will be either a Medical Officer of Health, Police Surgeon, Certifying Surgeon under the Factory and Workshops Act, Medical Referee under the Workmen’s Compensation Act, Physician or Surgeon in a big General Hospital, or a man specially appointed by the Cremation authorities. If you want to give any excuse for the search, you can say that you are compiling statistics about cancer; but what you really want is the names of the people concerned and the name of the town.”
