Caro was haunted, continually haunted, by the fact that she had injured me.
That knowledge never left her in peace. It colored all her actions. It explained her attitude to me. Nothing was too good for me. In her eyes, I must always come first.
Half the quarrels she had with Amyas were on my account."
Miss Warren paused, then went on.
"It was very bad for me, of course.
I got horribly spoiled.
But that's neither here nor there.
We're discussing the effect on Caroline.
The result of that impulse to violence was a lifelong abhorrence of any further act of the same kind.
Caro was watching herself, always in fear that something kind might happen again.
And she took her own of guarding against it.
One of those ways was a great of language.
She felt (and I think, quite truly) that if she were violent enough in speech she would have no temptation to violence in action.
She found by experience that the method worked.
"That's why I've heard Caro say things like,
'I'd like to cut so and so in pieces and boil him slowly in oil.'
And she'd say to me, or to Amyas,
'If you go on annoying me I shall murder you.'
In the same way she quarreled easily and violently. She recognized, I think, the impulse to violence that there was in her nature, and she deliberately gave it an outlet that way. She and Amyas used to have the most fantastic and lurid quarrels."
Hercule Poirot nodded.
"Yes, there was evidence of that. They quarreled like cat and dog, it was said."
Angela Warren said: "Exactly. That's what is so stupid and misleading about evidence.
Of course Caro and Amyas quarreled! Of course they said bitter and outrageous and cruel things to each other! What nobody appreciates is that they enjoyed quarreling.
But they did! Amyas enjoyed it, too.
They were that kind of couple.
They both of them liked drama and emotional scenes.
Most men don't. They like peace. But Amyas was an artist. He liked shouting and threatening and generally being outrageous.
It was like letting off steam to him. He was the kind of man who when he loses his collar stud bellows the house down.
It sounds very odd, I know, but living that way with continual rows and makings up was Amyas's and Caroline's idea of fun!" She made an impatient gesture.
"If they'd only not hustled me away and let me give evidence, I'd have told them that."
Then she shrugged her shoulders. "But I don't suppose they would have believed me.
And, anyway, then it wouldn't have been as clear in my mind as it is now.
It was the kind of thing I knew but hadn't thought about and certainly had never dreamed of putting into words." She looked across at Poirot. "You do see what I mean?"
He nodded vigorously.
"I see perfectly, and I realize the absolute rightness of what you have said. There are people to whom agreement is monotony. They require the stimulant of dissension to create drama in their lives." "Exactly."
"May I ask you, Miss Warren, what were your own feelings at the time?"
Angela Warren sighed.
"Mostly bewilderment and helplessness, I think.
It seemed a fantastic nightmare.
Caroline was arrested very soon - about three days afterward, I think, I can still remember my indignation, my dumb fury - and, of course, my childish faith that it was just a silly mistake, that it would be all right.
Caro was chiefly perturbed about me - she wanted me kept right away from it all as far as possible.
She got Miss Williams to take me away to some relations almost at once.
The police had no objection.
And then, when it was decided that my evidence would not be needed, arrangements were made for me to go to school abroad.
"I hated going, of course. But it was explained to me that Caro had me terribly on her mind and that the only way I could help her was by going." She paused. Then she said, "So I went to Munich. I was there when - when the verdict was given.
They never let me go to see Caro. Caro wouldn't have it.
That's the only time, I think, when she failed in understanding."
"You cannot be sure of that, Miss Warren.
To visit someone dearly loved in a prison might make a terrible impression on a young, sensitive girl."
"Possibly." Angela Warren got up. She said: "After the verdict, when she had been condemned, my sister wrote me a letter.
