When Maigret is reading the 'Letter to the Editor' about the escape, the position of his hands on the newspaper change between shots.

At 12:20 into the film [Odeon DVD edition], Kirby's girlfriend, in reference to the paper he is reading, asks him, "Did you hire that knife-grinder?" But she cannot possibly have read about any "knife-grinder", because, as the shot of the paper makes clear, the police have as yet no idea who committed the murders, and the arrest of the knife-grinder Heurtin has not yet taken place. It is not until five minutes later in the film, at 17:24, that the viewer sees a newspaper article indicating that the Heurtin has been charged with the murder. So either the scenes are (without any indication to the viewer) presented out of chronological order, which would be clumsy and confusing, or the script-writer is guilty of a continuity error.

Radek manages to climb from the ground almost to the top of the Eiffel tower, on the outside using the framework only, in record time using no climbing equipment and dressed in street clothes. Although the distance is actually only 300 meters, it would take even a professional climber at least a couple of hours as the headwinds and cross currents would make it hugely difficult and time consuming. Yet at times, Radek manages to climb faster than the tower elevator can move.
