"Come inside, please—on the left there. Won't you sit down, sir."

The tiny room was heavily overcrowded with a massive pseudo-Jacobean suite, but we managed to squeeze ourselves in and on to a hard-seated sofa.

"You must excuse me," the woman was saying. "I am sure I'm sorry I spoke so sharp just now, but you'd hardly believe the worry one has to put up with—fellows coming along selling this, that and the other—vacuum cleaners, stockings, lavender bags and suchlike foolery—and all so plausible and civil spoken. Got your name, too, pat they have. It's Mrs. Fowler this, that and the other."

Seizing adroitly on the name, Poirot said: "Well, Mrs. Fowler, I hope you're going to do what I ask."

"I don't know, I'm sure." The five pounds hung alluringly before Mrs. Fowler's eyes. "I knew Mrs. Ascher, of course, but as to writing anything."

Hastily Poirot reassured her. No labour on her part was required. He would elicit the facts from her and the interview would be written up.

Thus encouraged, Mrs. Fowler plunged willingly into reminiscence, conjecture and hearsay.

Kept to herself, Mrs. Ascher had. Not what you'd call really friendly, but there, she'd had a lot of trouble, poor soul, everyone knew that. And by right Franz Ascher ought to have been locked up years ago. Not that Mrs. Ascher had been afraid of him—a real tartar she could be when roused! Give as good as she got any day. But there it was—the pitcher could go to the well once too often. Again and again, she, Mrs. Fowler, had said to her: "One of these days that man will do for you. Mark my words." And he had done, hadn't he? And there had she, Mrs. Fowler, been right next door and never heard a sound.

In a pause Poirot managed to insert a question.

Had Mrs. Ascher ever received any peculiar letters—letters without a proper signature—just something like A.B.C.?

Regretfully, Mrs. Fowler returned a negative answer.

"I know the kind of thing you mean—anonymous letters they call them—mostly full of words you'd blush to say out loud. Well, I don't know, I'm sure, if Franz Ascher ever took to writing those. Mrs. Ascher never let on to me if he did. What's that? A railway guide, an A.B.C.? No, I never saw such a thing about—and I'm sure if Mrs. Ascher had been sent one I'd have heard about it. I declare you could have knocked me down with a feather when I heard about this whole business. It was my girl Edie what came to me. 'Mum,' she says, 'there's ever so many policemen next door.' Gave me quite a turn, it did. 'Well,' I said, when I heard about it, 'it does show that she ought never to have been alone in the house—that niece of hers ought to have been with her. A man in drink can be like a ravening wolf,' I said, 'and in my opinion a wild beast is neither more nor less than what that old devil of a husband of hers is. I've warned her,' I said, 'many times and now my words have come true. He'll do for you,' I said. And he has done for her! You can't rightly estimate what a man will do when he's in drink and this murder's a proof of it."

She wound up with a deep gasp.

"Nobody saw this man Ascher go into the shop, I believe?'' said Poirot.

Mrs. Fowler sniffed scornfully. "Naturally he wasn't going to show himself," she said.

How Mr. Ascher had got there without showing himself she did not deign to explain.

She agreed that there was no back way into the house and that Ascher was quite well known by sight in the district.

"But he didn't want to swing for it and he kept himself well hid."

Poirot kept the conversational ball rolling some little time longer but when it seemed certain that Mrs. Fowler had told all that she knew not once but many times over, he terminated the interview, first paying out the promised sum.

"Rather a dear five pounds' worth, Poirot," I ventured to remark when we were once more in the street.

"So far, yes."

"You think she knows more than she has told?"

"My friend, we are in the peculiar position of not knowing what questions to ask. We are like little children playing Cache Cache in the dark. We stretch out our hands and grope about. Mrs. Fowler has told us all that she thinks she knows—and has thrown in several conjectures for good measure! In the future, however, her evidence may be useful. It is for the future that I have invested that sum of five pounds."

I did not quite understand the point, but at this moment we ran into Inspector Glen.

Inspector Glen was looking rather gloomy. He had, I gathered, spent the afternoon trying to get a complete list of persons who had been noticed entering the tobacco shop.

"And nobody has seen anyone?" Poirot inquired.

"Oh, yes, they have. Three tall men with furtive expressions four short men with black moustaches—two beards—three fat men—all strangers—and all, if I'm to believe witnesses, with sinister expressions! I wonder somebody didn't see a gang of masked men with revolvers while they were about it!"

Poirot smiled sympathetically. "Does anybody claim to have seen the man Ascher?"

"No, they don't. And that's another point in his favour. I've just told the Chief Constable that I think this is a job for Scotland Yard. I don't believe it's a local crime."

Poirot said gravely: "I agree with you."

The inspector said: "You know, Monsieur Poirot, it's a nasty business—a nasty business . . . I don't like it . . . ."

We had two more interviews before returning to London.

The first was with Mr. James Partridge. Mr. Partridge was the last person known to have seen Mrs. Ascher alive. He had made a purchase from her at 5:30.

Mr. Partridge was a small, spare man, a bank clerk by profession. He wore pince-nez, was very dry and spare-looking and extremely precise in all his utterances. He lived in a small house as neat and trim as himself.

"Mr.—er—Poirot," he said, glancing at the card my friend had handed to him. "From Inspector Glen? What can I do for you, Mr. Poirot?"

"I understand, Mr. Partridge, that you were the last person to see Mrs. Ascher alive."

Mr. Partridge placed his fingertips together and looked at Poirot as though he were a doubtful cheque.

"That is a very debatable point, Mr. Poirot," he said. "Many people may have made purchases from Mrs. Ascher after I did so."

"If so, they have not come forward to say so."

Mr. Partridge coughed. "Some people, Mr. Poirot, have no sense of public duty."

He looked at us owlishly through his spectacles.

"Exceedingly true," murmured Poirot. "You, I understand, went to the police of your own accord?"

"Certainly I did. As soon as I heard of the shocking occurrence I perceived that my statement might be helpful and came forward accordingly.''

"A very proper spirit," said Poirot solemnly. "Perhaps you will be so kind as to repeat your story to me."

"By all means. I was returning to this house and at 5:30 precisely—"

"Pardon, how was it that you knew the time so accurately?"

Mr, Partridge looked a little annoyed at being interrupted. "The church clock chimed. I looked at my watch and found I was a minute slow. That was just before I entered Mrs. Ascher's shop."

"Were you in the habit of making purchases there?"

"Fairly frequently. It was on my way home. About once or twice a week I was in the habit of purchasing two ounces of John Ce[unreadable] mild."
