Taverner asked: "How good was your father's eyesight?"

"He suffered from glaucoma. He used strong glasses 5 of course 5 for reading."

"He had those glasses on that evening?"

"Certainly. He didn't take his glasses off until after he had signed. I think I am right?", b "Quite right," said Clemency.

"And nobody - you are all sure of that - went near the desk before the signing of the will?"

"I wonder now," said Magda, screwing up her eyes. "If one could only visualise it all again."

"Nobody went near the desk," said Sophia. "And grandfather sat at it all the time."

"The desk was in the position it is now?

It was not near a door, or a window, or any drapery?"

"It was where it is now.

"I am trying to see how a substitution of some kind could have been effected," said Taverner. "Some kind of substitution there must have been. Mr. Leonides was under the impression that he was signing the document he had just read aloud."

"Couldn't the signatures have been erased?" Roger demanded.

"No, Mr. Leonides. Not without leaving signs of erasion. There is one other possibility.

That this is not the document sent to Mr. Leonides by Gaitskill and which he signed in your presence."

"On the contrary," said Mr. Gaitskill. "I could swear to this being the original document. There is a small flaw in the paper - at the top left hand corner - it resembles, by a stretch of fancy, an aeroplane.

I noticed it at the time."

The family looked blankly at one another.

"A most curious set of circumstances," said Mr. Gaitskill. "Quite without precedent in my experience."

"The whole thing's impossible," said Roger. "We were all there. It simply couldn't have happened."

Miss de Haviland gave a dry cough. "Never any good wasting breath saying something that has happened couldn't have happened," she remarked. "What's tie position now? That's what I'd like to know?"

Gaitskill immediately became the cautious lawyer.

"The position will have to be examined very carefully," he said. "The document, of course, revokes all former wills and testaments. There are a large number of witnesses who saw Mr. Leonides sign wtiat he certainly believed to be this will in perfectly good faith. Hum. Very interesting.

Quite a little legal problem."

Taverner glanced at his watch.

"I'm afraid," he said, "I've been keeping you from your lunch."

"Won't you stay and lunch with us. Chief Inspector?" asked Philip, a?

"Thank you, Mr. Leonides, but I am meeting Dr. Cray in Swinly Dean."

Philip turned to the lawyer.

"You'll lunch with us, Gaitskill?"

"Thank you, Philip."

Everybody stood up. I edged unobtrusively towards Sophia.

"Do I go or stay?" I murmured. It sounded ridiculously like the title of a Victorian song.

"Go, I think," said Sophia.

I slipped quietly out of the room in pursuit ofTaverner. Josephine was swinging to and fro on a baize door leading to the back quarters. She appeared to be highly amused about something.

"The police are stupid," she observed.

Sophia came out of the drawing room.

"What have you been doing, Josephine?"

"Helping Nannie."

"I believe you've been listening outside the door."

Josephine made a face at her and retreated. 3;

"That child," said Sophia, "is a bit of a problem."

"So the kid told you?" said Taverner.

"She seems to be wise to everything that goes on in that house."

"Children usually are," said my father drily.

This information, if true, altered the whole position. If Roger had been, as Josephine had confidently suggested, "embezzling" the funds of Associated Catering and if the old man had found it out, it might have been vital to silence old Leonides and to leave England before the truth came out. Possibly Roger had rendered himself liable to criminal prosecution.

It was agreed that inquiries should be made without delay into the affairs of Associated Catering.

"It will be an almighty crash, if that goes," my father remarked. "It's a huge concern. There are millions involved."

"If it's really in Queer Street, it gives us what we want," said Taverner. "Father summons Roger. Roger breaks down and confesses. Brenda Leonides was out at a cinema. Roger has only got to leave his father's room, walk into the bathroom? empty out an insulin phial and replace it with the strong solution of eserine and there you are. Or his wife may have done it. She went over to the other wing after she came home that day - says she went over to fetch a pipe Roger had left there. But she could have gone over to switch the stuff before Brenda came home and gave him his injection. She'd be quite cool and capable about it."

I nodded. "Yes, I fancy her as the actual doer of the deed. She's cool enough for anything! And I don't think that Roger Leonides would think of poison as a means - that trick with the insulin has something feminine about it."

"Plenty of men poisoners," said my father drily.

"Oh, I know, sir," said Taverner. "Don't I know!" he added with feeling.

"All the same I shouldn't have said Roger was the type."

"Pritchard," the Old Man reminded him, "was a good mixer."

"Let's say they were in it together."

"With the accent on Lady Macbeth," said my father, as Taverner departed. "Is that how she strikes you, Charles?"'

I visualised the slight graceful figure standing by the window in that austere room.

"Not quite," I said. "Lady Macbeth was essentially a greedy woman. I don't think Clemency Leonides is. I don't think she wants or cares for possessions."

"But she might care, desperately, about her husband's safety?"

"That, yes. And she could certainly be - well, ruthless."

"Different kinds of ruthlessness…"

That was what Sophia had said.

I looked up to see the Old Man watching me.

"What's on your mind, Charles?"

But I didn't tell him then.

I was summoned on the following day and found Taverner and my father together.

Taverner was looking pleased with himself and slightly excited.

"Associated Catering is on the rocks," said my father.

"Due to crash at any minute," said Taverner.

"I saw there had been a sharp fall in the shares last night," I said. "But they seem to have recovered this morning."

"We've had to go about it very cautiously," said Taverner. "No direct inquiries.

Nothing to cause a panic - or to put the wind up our absconding gentleman. But we've got certain private sources of information and the information there is fairly definite. Associated Catering is on the verge of a crash. It can't possibly meet its commitments.

The truth seems to be that it's been grossly mismanaged for years."

"By Roger Leonides?"

"Yes. He's had supreme power, you know."

"And he's helped himself to money -"

"No," said Taverner. "We don't think he has. To put it bluntly, he may be a murderer, but we don't think he's a swindler.

Quite frankly he's just been - a fool. He doesn't seem to have had any kind of judgement. He's launched out where he should have held in - he's hesitated and retreated where he ought to have launched out. He's delegated power to the last sort of people he ought to have delegated it to.

He's a trustful sort of chap, and he's trusted the wrong people. At every time, and on every occasion, he's done the wrong thing."

"There are people like that," said my father. "And they're not really stupid either.

They're bad judges of men, that's all. And they're enthusiastic at the wrong time."

"A man like that oughtn't to be in business at all," said Taverner.

"He probably wouldn't be," said my father, "except for the accident of being Aristide Leonides's son."

"That show was absolutely booming when the old man handed it over to him. It ought to have been a gold mine! You'd think he could have just sat back and let the show run itself."

"No," my father shook his head. "No show runs itself. There are always decisions to be made - a man sacked here - a man appointed there - small questions of policy.

And with Roger Leonides the answer seems to have been always wrong."

"That's right," said Taverner. "He's a loyal sort of chap, for one thing. He kept on the most frightful duds - just because he had an affection for them - or because they'd been there a long time. And then he sometimes had wild impractical ideas and insisted on trying them out in spite of the enormous outlay involved."

"But nothing criminal?" my father insisted. 

"No, nothing criminal."

"Then why murder?" I asked.

"He may have been a fool and not a knave," said Taverner. "But the result was the same - or nearly the same. The only thing that could save Associated Catering from the smash was a really colossal sum of money by next" (he consulted a notebook) "by next Wednesday at the latest."

"Such a sum as he would inherit, or thought he would have inherited, under his father's will?"

"Exactly."

"But he wouldn't be able to have got that sum in cash."

"No. But he'd have got credit. It's the same thing."

The Old Man nodded.

"Wouldn't it have been simpler to go to old Leonides and ask for help?" he suggested 

"I think he did," said Taverner. "I think that's what the kid overheard. The old boy refused point blank, I should imagine, to throw good money after bad. He would, you know."

I thought that Taverner was right there.

Aristide Leonides had refused the backing for Magda's play - he had said that it would not be a Box Office success. Events had proved him correct. He was a generous nian to his family, but he was not a man to Waste money in unprofitable enterprises.

And Associated Catering ran to thousands, or probably hundreds of thousands. He had refused point blank, and the only way for Roger to avoid financial ruin was for his father to die.
