When political thugs murder an opponent's volunteer and also kill a cop, chief inspector Verjeat believes the politician who hired them is as guilty as the murderous goon.

He speeds up his hunt for the goon and, with Lefévre, one of his young detectives, he engineers a complicated scheme to buy more time before the transfer. How should Verjeat play out his values of honor and duty?
