“What’s the idea of this, Meadows—sending this bird to cross-examine me?”

“This bird came on his own,” said Meadows coldly, “if you mean Mr. Gonsalez? I have no right to prevent any person from cross-examining you. Where is the young lady?”

“I tell you she has gone home. If you don’t believe me, search the house—either of you.”

He was not bluffing: Leon was sure of that. He turned to the detective.

“I personally have no wish to trouble this gentleman any more.”

He was leaving the room when, from over his shoulder:

“That snake is busy again, Newton.”

“What snake are you talking about?”

“He killed a man to-night on the Thames Embankment. I hope it will not spoil Lisa Marthon’s evening.”

Meadows, watching the man, saw him change colour.
