In this third Fantômas episode Fandor steps into the limelight (while both Fantômas and Juve become less prominent), attempting to crack the mystery of crimes apparently committed by a dead man. In Les Vampires, director Louis Feuillade's follow-up to the Fantômas series, he created a protagonist much like the Fandor shown here: a sleuthing journalist determined to track down an elusive master criminal. This episode also has the flavor of a police procedural, with its emphasis on “scientific policing”, specifically the anthropometry system of the French police officer Alphonse Bertillon - inventor of the mug shot.
