"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?"

"Let's say I shouldn't be surprised if they were. I don't know it for a fact."

"Did Mr. Clayton suspect?"

"Arnold was an extraordinary person. He was all bottled up, if you know what I mean. I think he did know. But he was the kind of man who would never have let on. Anyone would think he was a dry stick with no feelings at all. But I'm pretty sure he wasn't like that underneath. The queer thing is that I should have been much less surprised if Arnold had stabbed Charles than the other way about. I've an idea Arnold was really an insanely jealous person."

"That is interesting."

"Though it's more likely, really, that he'd have done in Margharita. Oth.e.l.lo - that sort of thing. Margharita, you know, has an extraordinary effect on men."

"She is a good-looking woman," said Poirot with judicious understatement.

"It was more than that. She had something. She would get men all het up - mad about her - and turn round and look at them with a sort of wide-eyed surprise that drove them barmy."

"Une femme fatale."

"That's probably the foreign name for it."

"You know her well?"

"My dear, she's one of my best friends - and I wouldn't trust her an inch."

"Ah," said Poirot and shifted the subject to Commander McLaren.

"Jock? Old faithful? He's a pet. Born to be the friend of the family. He and Arnold were really close friends. I think Arnold unbent to him more than to anyone else. And of course he was Margharita's tame cat. He'd been devoted to her for years."

"And was Mr. Clayton jealous of him, too?"

"Jealous of Jock? What an idea! Margharita's genuinely fond of Jock, but she's never given him a thought of that kind. I don't think, really, that one ever would... I don't know why... It seems a shame. He's so nice."

Poirot switched to consideration of the valet. But beyond saying vaguely that he mixed a very good side car, Linda Spence seemed to have no ideas about Burgess, and indeed seemed barely to have noticed him.

But she was quite quick in the uptake.

"You're thinking, I suppose, that he could have killed Arnold just as easily as Charles could? It seems to me madly unlikely."

"That remark depresses me, madame. But then, it seems to me (though you will probably not agree) that it is madly unlikely - not that Major Rich should kill Arnold Clayton - but that he should kill him in just the way he did."

"Stiletto stuff? Yes, definitely not in character. More likely the blunt instrument. Or he might have strangled him, perhaps?"

Poirot sighed.

"We are back at Oth.e.l.lo. Yes, Oth.e.l.lo... you have given me there a little idea "

"Have I? What -" There was the sound of a latchkey and an opening door. "Oh, here's Jeremy. Do you want to talk to him, too?"

Jeremy Spence was a pleasant looking man of thirty-odd, well groomed, and almost ostentatiously discreet. Mrs. Spence said that she had better go and have a look at a ca.s.serole in the kitchen and went off, leaving the two men together.

Jeremy Spence displayed none of the engaging candor of his wife. He was clearly disliking very much being mixed up in the case at all, and his remarks were carefully noninformative. They had known the Claytons some time, Rich not so well. Had seemed a pleasant fellow. As far as he could remember, Rich had seemed absolutely as usual on the evening in question. Clayton and Rich always seemed on good terms. The whole thing seemed quite unaccountable.

Throughout the conversation Jeremy Spence was making it clear that he expected Poirot to take his departure. He was civil, but only just so.

"I am afraid," said Poirot, "that you do not like these questions?"

"Well, we've had quite a session of this with the police. I rather feel that's enough. We've told all we know or saw. Now - I'd like to forget it."

"You have my sympathy. It is most unpleasant to be mixed up in this. To be asked not only what you know or what you saw but perhaps even what you think?"

"Best not to think."

"But can one avoid it? Do you think, for instance, that Mrs. Clayton was in it, too? Did she plan the death of her husband with Rich?"

"Good lord, no." Spence sounded shocked and dismayed. "I'd no idea that there was any question of such a thing?"

"Has your wife not suggested such a possibility?"

"Oh Linda! You know what women are - always got their knife into each other. Margharita never gets much of a show from her own s.e.x - a darned sight too attractive. But surely this theory about Rich and Margharita planning murder - that's fantastic!"

"Such things have been known. The weapon, for instance. It is the kind of weapon a woman might possess, rather than a man."

"Do you mean the police have traced it to her - They can't have! I mean -"

"I know nothing," said Poirot truthfully, and escaped hastily.

From the consternation on Spence's face, he judged that he had left that gentleman something to think about!

"You will forgive my saying, M. Poirot, that I cannot see how you can be of a.s.sistance to me in any way."

Poirot did not answer. He was looking thoughtfully at the man who had been charged with the murder of his friend Arnold Clayton.

He was looking at the firm jaw, the narrow head. A lean brown man, athletic and sinewy. Something of the greyhound about him. A man whose face gave nothing away, and who was receiving his visitor with a marked lack of cordiality.

"I quite understand that Mrs. Clayton sent you to see me with the best intentions. But quite frankly, I think she was unwise. Unwise both for her own sake and mine."

"You mean?"

Rich gave a nervous glance over his shoulder. But the attendant warder was the regulation distance away. Rich lowered his voice.

"They've got to find a motive for this ridiculous accusation. They'll try to bring that there was an - a.s.sociation between Mrs. Clayton and myself. That, as I know Mrs. Clayton will have told you, is quite untrue. We are friends, nothing more. But surely it is advisable that she should make no move on my behalf."

Hercule Poirot ignored the point. Instead he picked out a word.

"You said this 'ridiculous' accusation. But it is not that, you know."

"I did not kill Arnold Clayton."

"Call it then a false accusation. Say the accusation is not true. But it is not ridiculous. On the contrary, it is highly plausible. You must know that very well."

"I can only tell you that to me it seems fantastic."

"Saying that will be of very little use to you. We must think of something more useful than that."

"I am represented by solicitors. They have briefed, I understand, eminent counsel to appear for my defence. I cannot accept your use of the word 'we.'"

Unexpectedly Poirot smiled.

"Ah," he said, in his most foreign manner, "that is the flea in the ear you give me. Very well. I go. I wanted to see you. I have seen you. Already I have looked up your career. You pa.s.sed high up into Sandhurst. You pa.s.sed into the Staff College. And so on and so on. I have made my own judgement of you today. You are not a stupid man."

"And what has all that got to do with it?"

"Everything! It is impossible that a man of your ability should commit a murder in the way this one was committed. Very well. You are innocent. Tell me now about your manservant Burgess."

"Burgess?"

"Yes. If you didn't kill Clayton, Burgess must have done so. The conclusion seems inescapable. But why? There must be a 'why?' You are the only person who knows Burgess well enough to make a guess at it. Why, Major Rich, why?"

"I can't imagine. I simply can't see it. Oh, I've followed the same line of reasoning as you have. Yes, Burgess had opportunity - the only person who had except myself. The trouble is, I just can't believe it. Burgess is not the sort of man you can imagine murdering anybody."

"What do your legal advisers think?"

Rich's lips set in a grim line.

"My legal advisers spend their time asking me, in a persuasive way, if it isn't true that I have suffered all my life from blackouts when I don't really know what I am doing!"

"As bad as that," said Poirot. "Well, perhaps we shall find it is Burgess who is subject to blackouts. It is always an idea. The weapon now. They showed it to you and asked you if it was yours?"

"It was not mine. I had never seen it before."

"It was not yours, no. But are you quite sure you had never seen it before?"

"No." Was there a faint hesitation. "It's a kind of ornamental toy - really - One sees things like that lying about in people's houses."

"In a woman's drawing room, perhaps. Perhaps in Mrs. Clayton's drawing room?"

"Certainly not!"

The last word came out loudly and the warder looked up.

"Tres bien. Certainly not - and there is no need to shout. But somewhere, at some time, you have seen something very like it. Eh? I am right?"

"I do not think so. In some curio shop... perhaps."

"Ah, very likely." Poirot rose. "I take my leave."

"And now," said Hercule Poirot, "for Burgess. Yes, at long last, for Burgess."

He had learned something about the people in the case, from themselves and from each other. But n.o.body had given him any knowledge of Burgess. No clue, no hint, of what kind of a man he was.

When he saw Burgess he realized why.
