"The confession may be forged," said the Advocate.

"Gautran's signature," said Vanbrugh, "will refute such a charge. He could write only his name, and documents can certainly be found bearing his signature, which can be compared with this."

"With that document in your possession," said the Advocate, speaking very slowly, "are you not afraid to be here with me--alone--knowing, if it state the truth, how much I have at stake?"

"Excellent!" exclaimed Vanbrugh. "What likenesses there are in human nature, and how thin the line that divides the base from the noble! Afraid? No--for if you lay a hand upon me, for whom you are no more than a match, I will rouse the house and denounce you. Restrain yourself and hear me out.

It may be that you deliberately made a study of me to see what use you could make of my weakness. However it was, I lived in the present, you in the future. The case is now reversed, and it is I who live in the future.

"I have said you were cold-hearted, and I do not suppose you will trouble yourself to deny it. Such as you are formed to rise, while we impulsive, reckless devils are pretty sure to tumble in the mud. But I never had such a fall as you are threatened with, and scapegrace, vagabond as I am, I am thankful not to have on my conscience what you have on yours.

"Now for certain facts.
