Un Honnête Commerçant plot
Brussels, a whole family is found murdered... Inspectors Bex and Denoote question Hubert Verkamen. Hubert pretends to be an honest businessman, but the police know full well that he is a dangerous drug smuggler. Bex and Denoote try to exhaust Hubert with all possible means and make him give up. During the relentless interrogation, Verkamen is aided by the ghost of Monsieur Chevalier, a former colleague from the underworld. The manipulation cannot be found where we would expect it: it is Verkamen who sifts the information he needs for his own business from the inspectors.
