“No,” said Hannasyde, “I have not.”

“You had better tell me all about it,” said Randall amiably. “I can see that you are all of you—ah, pregnant with news.”

“Really, Randall!” protested Mrs Matthews.

“They've found out what the poison was put into,” said Guy.

“Have they indeed? Well, that's very nice,” said Randall. “And what was it put into?”

Randall had led Stella to a chair, and seemed to be more interested in seeing her comfortably settled into it than in Guy's disclosure. It was just a moment before he spoke, and then he merely said: “Really? Some ingenious brain at work, apparently.”

“That's exactly what I was thinking,” said Guy. “Damned ingenious!”

Randall turned away from Stella, and regarded Guy with veiled amusement. “Well, don't stop,” he said encouragingly. “What else were you thinking?”

“I don't know that I was thinking of anything else,” said Guy slowly.
