And Meredith did make all those poisons!
Perhaps he really made them because he liked the idea of being able to kill someone one day.
He had to call attention to the stuff being taken so as to divert suspicion from himself.
But he himself was far the most likely person to have taken it.
He might, even, have liked getting Caroline hanged - because she turned him down long ago.
I think, you know, it s rather fishy what he says in his account of it all - how people do things that aren't characteristic of them.
Supposing he meant himself when he wrote that?"
Hercule Poirot said,
"You are at least right in this - not to take what has been written down as necessarily a true narrative.
What has been written may have been written deliberately to mislead."
"Oh, I know.
I've kept that in mind."
"Any other ideas?"
Carla said slowly,
"I wondered - before I'd read this - about Miss Williams.
She lost her job, you see, when Angela went to school.
And if Amyas had died suddenly, Angela probably wouldn't have gone after all.
I mean, if it passed off as a natural death - which it easily might have done, I suppose, if Meredith hadn't missed the coniine.
I read up on coniine and it hasn't any distinctive post-mortem appearances.
It might have been thought to be sunstroke.
I know that just losing a job doesn't sound a very adequate motive for murder.
But murders have been committed again and again for what seem ridiculously inadequate motives.
Tiny sums of money sometimes.
And a middle-aged, perhaps rather incompetent governess might have got the wind up and just seen no future ahead of her.
"As I say, that's what I thought before I read this.
But Miss Williams doesn't sound like that at all. She doesn't sound in the least incompetent -"
"Not at all.
She is still a very efficient and intelligent woman."
"I know. One can see that.
And she sounds absolutely trustworthy, too.
That's what has upset me really. Oh, you know - you understand. You don't mind, of course. All along you've made it clear it was the truth you wanted.
I suppose now we've got the truth!
Miss Williams is quite right. One must accept truth.
It s no good basing your life on a lie because it's what you want to believe.
All right, then - I can take it!
My mother wasn't innocent!
She wrote me that letter because she was weak and unhappy and wanted to spare me.
I don't judge her.
Perhaps I should feel like that, too.
I don't know what prison does to you.
And I don't blame her, either - if she felt so desperately about my father, I suppose she couldn't help herself. But I don't blame my father altogether, either.
I understand - just a little - how he felt. So alive and so full of wanting everything... He couldn't help it - he was made that way.
And he was a great painter.
I think that excuses a lot."
She turned her flushed, excited face to Hercule Poirot with her chin raised defiantly.
"So you are satisfied?" Poirot said.
"Satisfied?" said Carla Lemarchant. Her voice broke on the word.
Poirot leaned forward and patted her paternally on the shoulder.
"Listen," he said. "You give up the fight at the moment when it is most worth fighting. At the moment when I, Hercule Poirot, have a very good idea of what really happened."
Carla stared at him.
