"I hear," said the barrister, smoking phlegmatically. "I am surety for Hench's good faith. You shall be paid, you rat. Now prove to us that you can have the woman arrested."

Spruce drew a long breath of relief, as things were now going exactly as he wished. Like the traitor he was, he gaily went to work and sold Madame Alpenny's secret to gain the money. "She came down to see Evans after she knew that Hench was his nephew."

"I know that," said Owain quickly. "Tell us something new."

"All in good time," said Spruce smoothly. "I made her confess how she arranged with Evans about the advertisement and how to draw your attention to it."

"Why was the appointment made in Parley Wood instead of in the house?" asked Vane, whom the problem had frequently perplexed.

"I can't tell you. Madame Alpenny never explained that to me. All I know is that she laid the trap for Hench to fall into, and he did."

"Only to find that my uncle was dead."

"Of course," said Spruce, turning towards Hench with raised eyebrows; "that was the trap. She intended to accuse you, and thus force you to marry Zara so that she could handle the money."

"That I also know, and she did accuse me. Well?"

"Well, she came down here by the same train as you did, and while you were at the Bull Inn she went on to Parley Wood and murdered the Squire."
