Johnny Thompson’s recollection of that affair in the tunnel will always remain decidedly vague. A wild face, a fleeing form, a voice in the dark, a terrific explosion, and after that darkness and silence.

“Marking time,” he sighed. “Doing nothing of real use. All our knowledge of crime and criminals going to waste. And still the crime wave goes merrily on. Three killings so far this week.
