Quote

"Don't come back until you have him", the Tick-Tock Man said quietly,
sincerely, extremely dangerously.

They used dogs. They used probes. They used cardio plate crossoffs.
They used teepers. They used bribery. They used stick tites. They
used intimidation. They used torment. They used torture. They used
finks. They used cops. They used search and seizure. They used
fallaron. They used betterment incentives. They used finger prints.
They used the bertillion system. They used cunning. They used guile.
They used treachery. They used Raoul-Mitgong but he wasn't much help.
They used applied physics. They used techniques of criminology. And
what [do you know], they caught him.

-- Harlan Ellison, "Repent, Harlequin, said the Tick-Tock Man"
