The Alzheimer Case, also known as The Alzheimer Affair or The Memory of a Killer, Dutch: De Zaak Alzheimer, is a 2003 film directed by Erik Van Looy, based on the novel De Zaak Alzheimer by Jef Geeraerts. Ledda, a former hitman for organized crime, agrees to a last killing, despite his recently developed Alzheimer's disease. He is to kill two people; on killing the first and recovering a package from the first victim, he then learns the second victim is Bieke, a twelve-year-old girl pimped by her father, who had been recently busted, but then killed by police trying to escape. Ledda refuses to kill a child. Resultantly, his employer, Seynaeve, has another hitman kill Bieke and orders him to kill Ledda. Ledda kills the hitman first but only after the hitman kills a prostitute who had befriended him.
