“Would not a mock one be just as effective in the mind of the unfortunate young lady?” I suggested.

“No, there are reasons why a legal marriage should take place,” he answered distinctly.

“And they are?”

“Ah! upon that point I regret that I cannot satisfy you,” he answered. “Is not twenty thousand pounds sufficient to satisfy you, without asking questions?”

“But I cannot see how a legal marriage can take place,” I queried. “There are surely formalities to be observed.”

“Leave them all to me,” he answered quickly. “Rest assured that I have overlooked no detail in this affair. A mock marriage would, of course, have been easy enough; but I intend that Beryl shall be legally wedded, and for the service rendered me by becoming her husband I am prepared to pay you twenty thousand pounds the instant the ceremony is concluded.”

Then, unlocking a drawer in his writing-table, he drew forth a large bundle of notes secured by an elastic band, which he held towards me, saying—

“These are yours if you care to accept my offer.”

I glanced at the thick square packet of crisp notes, and saw that each was for one hundred pounds. My eyes wandered to the Tempter’s face. The look I saw there startled me. Was he actually the devil in human guise?

He noticed the quick start I gave, and instantly his features relaxed into a smile.
