He had two "perfect" killings to his credit - but Nero Wolfe, never stirring from his old New York brownstone, had been able to tell the police how they had been done, and where they'd find the evidence.

The  next step would be for Wolfe to tell them who - and the murderer meant to see that Nero was very, very dead before  he got the chance.

Wolfe never left home . . . so the killer had to trap him there.  And he set the trap with a fantastic bait . . . a drawer filled with beer-bottle caps!
