The Tube/L'ingénieur aimait trop les chiffres [1958] – ★★★1/2
Boileau-Narcejac, a pen name of French crime writers Pierre Boileau and Thomas Narcejac, may be known for their books D’entre les morts and Celle qui n'était plus, that were successfully adapted into major films Vertigo and Les Diaboliques, but their other thriller output is also worth checking out.
The Tube/L'ingénieur aimait trop les chiffres centres around an atomic energy research centre in Paris where one of the leading engineers, Sorbier, is found dead, presumably murdered by a gunshot. This seems to be an impossible crime since the murderer could not have possibly escaped after the crime - the window area below Sorbier’s office was guarded, and another exit also had eyewitnesses standing nearby. And, what about the mysterious letter received by the deceased just before he died? Can it shed clues as to the identity of the murderer? Moreover, a potentially dangerous object of some great research value is found stolen from Sorbier’s office – a tube/cylinder that can be activated to lead to a great explosion. Inspector Mareuil (not that dissimilar to Simenon’s Inspector Maigret) takes this case, questioning Sorbier’s co-workers Renardeau and Belliard, as well as Sorbier’s beautiful wife Linda. More mysteries emerge, including other “impossible” murders, and the point of Boileau-Narcejac was also probably to show the increased technocratization of the society where humane principles become sidelined and forgotten. The crime resolution is a little too straightforward and unbelievable in this case, but this detective thriller still presents an intriguing conundrum and is a page-turner with a unique setting.
