10 More Times The Movie Killer Was Hiding In Plain Sight

10. Ransom Drysdale - Knives Out

Rian Johnson returned from a Galaxy, Far, Far Away with Knives Out, a homage to the classic Agatha Christie whodunits, replete with Poirot-esque super sleuth, Benoir Blanc. It's also immensely refreshing to see Chris Evans ditching the stars and stripes for a drinking, swearing wannabe playboy.

When kindly but naive nurse Marta believes she has accidentally given billionaire publisher Harlan Thrombey a lethal injection of morphine, she accepts the help of devious nephew Ransom Drysdale, who blackmails Marta for a share of the inheritance she alone will receive, believing he has successfully framed her for the murder.

Johnson kept us guessing as to Ransom's true nature, but he was considerate enough to place multiple clues throughout, including this easily missed but massive giveaway: When Marta is sitting in Ransom's apartment, one of the five large brown glass jugs is clearly missing. The flammable liquid inside was enough to torch the coroner's office, destroying the toxicology report and the only evidence of Marta's innocence.

Grandma also serves up a whopper: "Ransom, are you back again already?" she asks, watching Marta climbing down the trellis, mistaking her for Ransom. Why? Because Grandma had already seen Ransom climbing the walls that very night, sneaking in to switch Harlan's medication.

Johnson even straight out tells us who the killer is: "You did this!" croaks Fran as Marta attempts to save her life, except that's not exactly what she says. "HUGH did this!" is really the line, so what does that prove? Ransom's real name is Hugh.
