“Have you found out what it was?”
“Oh, arsenic, of course. Quite a fair dose he must have had. It’s queer how they always will use arsenic.”
Eden stared at him. “What are we to do?” he said in a low voice. “Fortune, I suppose it couldn’t have been accidental?”
“What is a child likely to eat in which he would find grains of accidental arsenic?”
“Yes, but then—— I mean, who could want to kill that child?”
“That is the unknown quantity in the equation. But people do want to murder children, quite nice children.”
Eden grew pale. “What do you mean? You know he’s not Warnham’s child. Warnham’s his step-father.”
“Yes. Yes. Have you ever seen the two together?”
Eden hesitated. “He—well, he didn’t seem to take to Warnham. But I’d have sworn Warnham was fond of him.”
“And that’s all quite natural, isn’t it? Well, well. I hope he’s in.”
