"Columbo Goes To The Guillotine": now that was committing to his theory of the criminal's plan.
OMG Ted that was the ultimate chance by Columbo. I often wonder before he had E. Blake put the collar on him if he had not taken out the blade thus making both sides of the collar safe. But left the stickers on there anyway. I would never put my head on the chopping block just a catch a killer if I was a police lieutenant.
