"You'd be surprised. I once knew a woman like that. Put a couple of husbands out of the way without a blink of her innocent blue eyes. Broken-hearted each time, too. The jury would have aquitted her if they'd had half a chance which they hadn't, the evidence being practically cast iron."

"Well, my friend, let us not argue. What I make so bold as to ask is a few reliable details on the facts. What a newspaper prints is news - but not always truth!"

"They have to enjoy themselves. What do you want?"

"Time of death as near as can be."

"Which can't be very near because the body wasn't examined until the following morning. Death is estimated to have taken place from thirteen to ten hours previously. That is, between seven and ten o'clock the night before... He was stabbed through the jugular vein - death must have been matter of moments."

"And the weapon?"

"A kind of Italian stiletto - quite small - razor sharp. n.o.body has ever seen it before, or knows where it comes from. But we shall know - in the end it's a matter of time and patience."

"It could not have been picked up in the course of a quarrel."

"No. The valet says no such thing was in the flat."

"What interests me is the telegram," said Poirot. "The telegram that called Arnold Clayton away to Scot- land. Was that summons genuine?"

"No. There was no hitch or trouble up there. The land transfer, or whatever it was, was proceeding normally."

"Then who sent that telegram - I am presuming there was a telegram?"

"There must have been. Not that we'd necessarily believe Mrs. Clayton. But Clayton told the valet he was called by wire to Scotland. And he also told Commander McLaren."

"What time did he see Commander McLaren?"

"They had a snack together at their club - Combined Services - that was at about a quarter past seven. Then Clayton took a taxi to Rich's flat, arriving there just before eight o'clock. After that -" Miller spread his hands out.

"Anybody noticed anything at all odd about Rich's manner that evening?"

"Oh well, you know what people are. Once a thing has happened, people think they noticed a lot of things I bet they never saw at all. Mrs. Spence, now, she says he was distrait all the evening. Didn't always answer to the point. As though he had 'something on his mind.' I bet he had, too, if he had a body in the chest! Wondering how the h.e.l.l to get rid of it!"

"Why didn't he get rid of it?"

"Beats me. Lost his nerve, perhaps. But it was madness to leave it until the next day. He had the best chance he'd ever have that night. There's no night porter on. He could have got his car round, packed the body in the boot - it's a big boot - driven out in the country and parked it somewhere. He might have been seen getting the body into the car, but the flats are in a side street and there's a courtyard you drive a car through. At, say, three in the morning, he had a reasonable chance. And what does he do? Goes to bed, sleeps late the next morning and wakes up to find the police in the flat!"

"He went to bed and slept well as an innocent man might do."

"Have it that way if you like. But do you really believe that yourself?"

"I shall have to leave that question until I have seen the man myself."

"Think you know an innocent man when you see one? It's not so easy as that."

"I know it is not easy - and I should not attempt to say I could do it. What I want to make up my mind about is whether the man is as stupid as he seems to be."

Poirot had no intention of seeing Charles Rich until he had seen everyone else.

He started with Commander McLaren.

McLaren was a tall, swarthy, uncommunicative man. He had a rugged but pleasant face. He was a shy man and not easy to talk to. But Poirot persevered.

Fingering Margharita's note, McLaren said almost reluctantly: "Well, if Margharita wants me to tell you all I can, of course I'll do so. Don't know what there is to tell, though. You've heard it all already. But whatever Margharita wants - I've always done what she wanted - ever since she was sixteen. She's got a way with her, you know."

"I know," said Poirot. He went on. "First I should like you to answer a question quite frankly. Do you think Major Rich is guilty?"

"Yes, I do. I wouldn't say so to Margharita if she wants to think he's innocent, but I simply can't see it any other way. Hang it all, the fellow's got to be guilty."

"Was there bad feeling between him and Mr. Clayton?"

"Not in the least. Arnold and Charles were the best of friends. That's what makes the whole thing so extraordinary."

"Perhaps Major Rich's friendship with Mrs. Clayton -"

He was interrupted.

"Faugh! All that stuff. All the papers slyly hinting at it. d.a.m.ned innuendoes! Mrs. Clayton and Rich were good friends and that's all! Margharita's got lots of friends. I'm her friend. Been one for years. And nothing the whole world mightn't know about it. Same with Charles and Margharita."

"You do not then consider that they were having an affair together?"

"Certainly not!" McLaren was wrathful. "Don't go listening to that h.e.l.lcat Spence woman. She'd say anything."

"But perhaps Mr. Clayton suspected there might be something between his wife and Major Rich."

"You can take it from me he did nothing of the sort! I'd have known if so. Arnold and I were very close."

"What sort of man was he? You, if anyone, should know."

"Well, Arnold was a quiet sort of chap. But he was clever - quite brilliant, I believe. What they call a first-cla.s.s financial brain. He was quite high up in the Treasury, you know."

"So I have heard."

"He read a good deal. And he collected stamps. And he was extremely fond of music. He didn't dance, or care much for going out."

"Was it, do you think, a happy marriage?"

Commander McLaren's answer did not come quickly. He seemed to be puzzling it out.

"That sort of thing's very hard to say... Yes, I think they were happy. He was devoted to her in his quiet way. I'm sure she was fond of him. They weren't likely to split up, if that's what you're thinking. They hadn't, perhaps, a lot in common."

Poirot nodded. It was as much as he was likely to get. He said: "Now tell me about that last evening. Mr. Clayton dined with you at the club. What did he say?"

"Told me he'd got to go to Scotland. Seemed vexed about it. We didn't have dinner, by the way. No time. Just sandwiches and a drink. For him, that is. I had only the drink. I was going out to a buffet supper, remember."

"Mr. Clayton mentioned a telegram?"

"Yes."

"He did not actually show you the telegram?"

"No."

"Did he say he was going to call on Rich?"

"Not definitely. In fact he said he doubted if he'd have time. He said, 'Margharita can explain or you can,' And then he said, 'See she gets home all right, won't you?' Then he went off. It was all quite natural and easy."

"He had no suspicion at all that the telegram wasn't genuine?"

"Wasn't it?" Commander McLaren looked startled.

"Apparently not."

"How very odd -" Commander McLaren went into a kind of coma, emerging suddenly to say: "But that really is odd. I mean, what's the point? Why should anybody want him to go to Scotland?"

"It is a question that needs answering, certainly."

Hercule Poirot left, leaving the commander apparently still puzzling on the matter.

The Spences lived in a minute house in Chelsea.

Linda Spence received Poirot with the utmost delight.

"Do tell me," she said. "Tell me all about Margharita! Where is she?"

"That I am not at liberty to state, madame."

"She has hidden herself well! Margharita is very clever at that sort of thing. But she'll be called to give evidence at the trial, I suppose? She can't wiggle herself out of that."

Poirot looked at her appraisingly. He decided grudgingly that she was attractive in the modern style (which at that moment resembled an underfed orphan child). It was not a type he admired. The artistically disordered hair fluffed out round her head, a pair of shrewd eyes watched him from a slightly dirty face devoid of makeup save for a vivid cerise mouth. She wore an enormous pale yellow sweater hanging almost to her knees, and tight black trousers.

"What's your part in all this?" demanded Mrs. Spence. "Get the boyfriend out of it somehow? Is that it? What a hope!"

"You think then, that he is guilty?"

"Of course. Who else?"

That, Poirot thought, was very much the question. He parried it by asking another question.

"What did Major Rich seem like to you on that fatal evening? As usual? Or not as usual?"

Linda Spence screwed up her eyes judicially.

"No, he wasn't himself. He was - different."

"How different?"

"Well, surely, if you've just stabbed a man in cold blood -"

"But you were not aware at the time that he had just stabbed a man in cold blood, were you?"

"No, of course not."

"So how did you account for his being 'different'? In what way?"

"Well - distrait. Oh, I don't know. But thinking it over afterwards I decided that there had definitely been something."

Poirot sighed.

"Who arrived first?"

"We did, Jim and I. And then Jock. And finally Margharita."

"When was Mr. Clayton's departure for Scotland first mentioned?"

"When Margharita came. She said to Charles: 'Arnold's terribly sorry. He's had to rush off to Edinburgh by the night train.' And Charles said: 'Oh, that's too bad.' And then Jock said: 'Sorry. Thought you already knew.' And then we had drinks."

"Major Rich at no time mentioned seeing Mr. Clayton that evening? He said nothing of his having called in on his way to the station?"

"Not that I heard."

"It was strange, was it not," said Poirot, "about that telegram?"

"What was strange?"

"It was a fake. n.o.body in Edinburgh knows anything about it."

"So that's it. I wondered at the time."

"You have an idea about the telegram?"

"I should say it rather leaps to the eye."

"How do you mean exactly?"

"My dear man," said Linda. "Don't play the innocent. Unknown hoaxer gets the husband out of the way! For that night, at all events, the coast is clear."

"You mean that Major Rich and Mrs. Clayton planned to spend the night together."

"You have heard of such things, haven't you?"

Linda looked amused.

"And the telegram was sent by one or the other of them?"

"It wouldn't surprise me."

"Major Rich and Mrs. Clayton were having an affair together you think?"
