As he brooded, the vision of Dyckman's money grew huger and huger. The dog had not merely thousands or hundreds of thousands, but thousands of thousands. Gilfoyle had never seen a thousand-dollar bill. Yet Dyckman, he had heard, was worth twenty millions. If his wealth were changed into thousand-dollar bills there would be twenty thousand of them in a stack.

If Gilfoyle peeled off one thousand of those thousand-dollar bills the stack would not be perceptibly diminished. If Gilfoyle could get a million dollars from Dyckman, or any part of it, Dyckman would never notice it; and yet it would mean a life of surety and poetry and luxury for Gilfoyle.

If he caught Dyckman and Anita together in a compromising situation he could collect heavily under threat of exposure. Rather than be dragged into the newspapers and the open courts Dyckman would pay almost any sum.

There was a law in New York against the violation of the seventh commandment, and the penitentiary was the punishment. The law had failed to catch its first victim, but it had been used in Massachusetts with success. The threat against Dyckman would surely work.

Then there was the recent Mann Law aimed at white-slavery but a more effective weapon for blackmailers. If Gilfoyle could catch Dyckman taking Anita motoring across the State line into New Jersey or Connecticut he could arrest them or threaten them.

Also he could name Dyckman as co-respondent in a divorce suit—or threaten to—and collect heavily that way. This was not blackmail in Gilfoyle's eyes. He scorned such a crime. This was honorable and necessary vindication of his offended dignity. There was probably never a practiser of blackmail who did not find a better word for the duress he applied.

Gilfoyle needed help. He had no cash to hire a detective with. But he knew a detective or two who might go into the thing with him on spec'.

Gilfoyle began to compose a scheme of poetic revenge. It should be his palinode to Anita. He would keep her under surveillance, but he would not let her know of his propinquity. A happy thought delighted him. To throw her off her guard, he wrote and sent a little note:

DEAR ANITA,—Since you evidently don't love me any longer, I will not bother you any more. I am taking the train back to Chicago. Address me there care of General Delivery if you ever want to see me again.

YOUR ONCE LOVED HUSBAND.
