He would have followed those people and demanded them. But Lawrence held him back until his passion was spent. He yielded suddenly.

"After all it matters little," he said.

"It matters a great deal," Lawrence replied. "You want your jewels back----"

"My dear sir, the first beggar in the street can have them for all I care."

"Well, you don't want those people to get them. Neither will they for long. It is all part of my little scheme. If you had dashed out just now you would certainly have caused a great sensation, and there would have been a great gap in the dazzling ranks of fashion, but you would have ruined my plans."

"But will those people be punished eventually?"

"Of course they will. But there are viler crimes than the theft of diamonds. There is the conspiracy to rob a good man of his good name, to make the lives of that man and the girl he is going to marry dark for the sake of a passing caprice. I tell you this has been done, and a murder has been committed in the doing of it. And I am going to get to the bottom of the foul tangle."

It was not the usual voice of Gilbert Lawrence that spoke. There was a dogged grimness about him that would have surprised his friends. "Let us light the gas and smoke here for a time," he said. "There is not the slightest chance of those people coming back, and there are no windows overlooking this one. I have a good deal to say to you."

Charlton made no objection. He was evidently in the company of a man who knew quite well what he was doing.

"I will be guided entirely by you," he said. "You tell me that that vile woman will be punished, and I believe you. Strange that she should be mixed up with the lives of people you care for also. You must have been sure of your ground to let her escape you tonight."
