Suspect X

Suspect X (2008) is Hiroshi Nishitani's Japanese mystery, available to watch online on iFILM. A faceless body with burned fingertips turns up in a park, yet the cause of death is strangulation, not the disfigurement.

The prime suspect is the victim's ex-wife, but her alibi holds airtight to the minute. Detective Kaoru Utsumi turns to physicist Manabu Yukawa, who recognizes the widow's next-door neighbor — Ishigami, a brilliant, lonely math teacher from his university days. The deeper they dig, the clearer it gets: this puzzle was built by a mind, not a killer.

The film adapts Keigo Higashino's novel The Devotion of Suspect X, one of Japan's most celebrated crime stories. Masaharu Fukuyama reprises Yukawa from the Galileo series, but the real engine isn't whodunit — it's a duel between two mathematicians and the question of how far love will go. Cold, precise filmmaking for fans of cerebral mysteries. Stream Suspect X (2008) online on iFILM.
