“I know. And I didn't mean that. I don't see how you could have done it. What does that Superintendent think?”

“He, like you, sweetheart, doesn't see how I could have done it. It disheartens him, I'm afraid.”

“Randall, will they ever find out who did it?”

“Why ask me?” he countered.

“Because you know something. It's no good saying you don't. I don't see how you could have murdered uncle, but I'm certain you're hiding some fact, or clue, or something which you don't want anyone to get hold of. I haven't forgotten that I saw you coming out of uncle's room that day. You were looking for something.”

“I was,” said Randall imperturbably. “But I didn't find it.”

“What was it?” she asked. “I don't know.”

“Don't know?”

“Not yet. I was looking for something that might have contained the poison. I admit it was a forlorn hope.”

“I don't think I altogether believe you,” said Stella.
