The best Jacques Denis’s mystery movies

The film's plot is based on the Kennedy assassination and subsequent investigation. The film begins with the assassination of President Marc Jarry, who is about to be inaugurated for a second six-year term of office. Henri Volney, state attorney and member of the commission charged with investigating the assassination (based on the Warren Commission) refuses to agree to the commission's final findings. The film portrays the initial controversy about this, as well as Volney and his staff's reopening of the investigation.

French filmmaker Claude Miller's This Sweet Sickness is based on a suspense novel by Patricia Highsmith, of Strangers on a Train fame. In the original, the murder-protagonist was a psychotic, pure and simple (if such words are appropriate here!) In Miller's version, the "hero," David, is a pathetic creature, motivated by humiliation and sexual inadequacy; thus the emphasis is not on his heinous crimes but on his warped personality. The director's noirish decision to stage much of the action in the dark, or the rain, or both, is a function of David's deep depression. As in his other films, Miller uses water as an omen of evil; you've seldom seen a more foreboding swimming pool than the one in This Sweet Sickness. The film was originally released as Dites-lui que je l'aime.
