There was one other thing I noticed about her. She looked frightened.
"Good morning, Mrs Leonides," said Taverner easily. "I'm sorry to have to trouble you again."
She said in a flat voice:
"I suppose it can't be helped."
"You understand, don't you, Mrs Leonides, that if you wish your solicitor to be present, that is perfectly in order."
I wondered if she did understand the significance of those words.
Apparently not.
She merely said rather sulkily:
"I don't like Mr Gaitskill.
I don't want him."
"You could have your own solicitor, Mrs Leonides."
"Must I?
I don't like solicitors.
They confuse me."
"It's entirely for you to decide," said Taverner, producing an automatic smile. "Shall we go on, then?"
Sergeant Lamb licked his pencil.
Brenda Leonides sat down on a sofa facing Taverner.
"Have you found out anything?" she asked.
I noticed her fingers nervously twisting and untwisting a pleat of the chiffon of her dress.
"We can state definitely now that your husband died as a result of eserine poisoning."
"You mean those eyedrops killed him?"
"It seems quite certain that when you gave Mr Leonides that last injection, it was eserine that you injected and not insulin."
"But I didn't know that.
I didn't have anything to do with it.
Really I didn't, Inspector."
"Then somebody must have deliberately replaced the insulin by the eyedrops."
"What a wicked thing to do!"
"Yes, Mrs Leonides."
"Do you think - someone did it on purpose?
Or by accident?
It couldn't have been a - a joke, could it?"
Taverner said smoothly:
"We don't think it was a joke, Mrs Leonides."
"It must have been one of the servants."
Taverner did not answer.
"It must.
I don't see who else could have done it."
"Are you sure?
Think, Mrs Leonides.
Haven't you any ideas at all?
There's been no ill feeling anywhere?
No quarrel?
No grudge?"
She still stared at him with large defiant eyes.
"I've no idea at all," she said.
"You had been at the cinema that afternoon, you said?"
"Yes - I came in at half past six - it was time for the insulin - I - I - gave him the injection just the same as usual and he went all queer. I was terrified - I rushed over to Roger - I've told you all this before.
Have I got to go over it again and again?" Her voice rose hysterically.
"I'm so sorry, Mrs Leonides.
Now can I speak to Mr Brown?"
