"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. Damned 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 hellcat 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-class 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?"
