This episode is oddly linked to a (highly presumed unsolved) case of a kidnapped & murdered 8 years old girl in Marseille, as it is officially presented as
Christian Ranucci's time-schedule for the evening of Monday June 3rd. 1974 after his long weekend trip in his newly bought used car (meaning time-schedule for the eve of the genuine & actual airing).
Wondering who did tell
Gilles Perrault about the movie title included in this episode; movie title clearly written down in his book (adapted for the screen by
Michel Drach as
Le pull-over rouge (1979)).
