"It all comes back now. You were a member of the class of '14 and I was instructor—a major then. I took all of you to see a certain show on Broadway, as they call it, in order...."
"Yes, sir," cried Neville, eagerly, "that was it! You told us the principal character in the play was the most dangerous potential criminal of our generation and that we should mark him well and remember. It was a very hard assignment, for we only saw him from before the foot-lights and he was acting the part of a Viking chieftain and most of his face was covered with false white whiskers."
Old O'Hara smiled.
"You seem to have been an apt pupil. At any rate, that man was Milo Lunko, a thoroughly unprincipled and remarkably clever blackmailer. He was so clever, in fact, that we were never able to make an arrest stick, let alone bring him to trial. That accounts for the absence of his picture from the gallery. He was also clever enough to fake his own death. The evidence we have as to that was so convincing we closed the file on him."
"It's open again," said Neville grimly. "How did he work?"
"Lunko was not only an actor, but a producer and clever playwright as well. He might have achieved fame and fortune legitimately, but he became greedy. He teamed up with a shady character named Krascbik who ran a private investigating agency, specializing in social scandals. Krascbik's men would study the private life of influential individuals and dig out their scandals. They would provide Lunko with slow-motion camera studies of them so he could learn the peculiarities of their carriage, mannerisms, voice, and all their other idiosyncracies.
"Lunko's next step would be to write a scurrilous play based on the confidential information provided by Krascbik, and put it in rehearsal, using characters that resemble the actual principals...."
"But that's libel," objected Neville, "why couldn't you haul him in?"
"Blackmail, young man, is a delicate matter to handle. The injured party shrinks from publicity and usually prefers to pay rather than have his scandal aired. Lunko never actually publicly produced any of those nauseous plays. His trick was to invite the victim to a preview—a dress rehearsal, then let Nature take its course. Invariably, the victim was frightened and tried to induce him to call off the presentation. Lunko would protest that the play had been written in good faith and had already cost him a great deal of money. The pay-off, of course, was always big. Lunko drove many people to the brink of ruin.
