What I can't understand is how this thief can imitate me so perfectly. It has to be someone who knew every detail of my technque. Maybe somebody in the police...He picks perfect victims and only the right stones. Goes up walls, over the roofs, down through the skylights. Leaves no clue and then disappears in the night...If somebody caught this imitator, we'd all be off the hook, wouldn't we?...No one believes me, but the police are chasing the wrong man. Someone's got to start chasing the right one...I've got to catch this imitator myself...I can anticipate him, try to figure out his next move, and then get there ahead of him and catch him with his hands right in the jewel case...The biggest problem is time. I've got to hit this copy-cat before he hears I'm after him. To catch him in the act, I need better information than he has, the kind that takes months to dig out.
