"It is curious," I said, "that a real intellect should care to spend part of its time in rake-helling round the low clubs, the gambling-rooms and stage-doors of London. Such a thing is known, but it is rare."

"You put your finger instantly upon what seems a weak spot in my character sketch. But let us assume that it has been done with a deep motive."

"Ah!" He knew, or suspected, something more. He referred to his notebook.

"Two years ago a certain Mr. Herbert Gascoigne was expelled from Christ Church College, Oxford."

"Sent down, we call it; but go on."

"The case was a bad one. The young man had established a sort of gambling club and ruined several of his contemporaries. It was discovered that he was using a roulette wheel that had been tampered with. He came to London and drifted into the worst gang of swindlers. Major Helzephron met him. They became very friendly. The younger man was obviously under the influence of the elder. Finally Gascoigne deserted his old haunts and has disappeared."

I began to see light.

"On several occasions my astute friend, Mr. Brookfield, has witnessed precisely the same phenomenon. Some young man of the upper classes has been ruined socially, and our enigmatic friend has taken him up, been seen about with him, and so forth. Finally the young man vanishes."

"It is not philanthropy, Mr. Danjuro."

"It is not, and it gives rise to curious speculations. Where could a Napoleonic criminal, patiently planning and meditating a stupendous coup, find a better recruiting ground than among the desperate and ruined young men of his own class? The plan is in itself evidence of genius. They speak his language, he understands their way of thought; there are a thousand bonds between them. I can conceive no more solid and formidable combination than just this. The one last virtue remaining to these desperate and outcast young men will be loyalty to their leader. Society has cast them out, therefore they will make war on Society. Given that attitude of mind, a leader like Major Helzephron, and a plan so daring, and the thing becomes plain as daylight. And if this man had not fallen into an overmastering passion for Miss Shepherd there would have been no means of getting on his trail at all."
