Shortly afterward, Sam is contacted by both Marion's sister Lila Crane (Vera Miles) and private detective Milton Arbogast (Martin Balsam), who has been hired by Marion's employer to recover the money. Arbogast traces Marion to the motel and questions Norman, who unconvincingly lies that Marion stayed for one night and left the following morning. He refuses to let Arbogast talk to his mother, claiming she is ill. Arbogast calls Lila to update her and tells her he will call again after he questions Norman's mother.
