Homicidal is a 1961 American horror-thriller film produced and directed by William Castle, and starring Glenn Corbett, Patricia Breslin, Eugenie Leontovich, Alan Bunce and Jean Arless. The film follows a murderous woman in a small California town whose presence unearths secrets concerning a prominent local family. As with many of Castle's films, the film was released with a promotional gimmick—in this case, a "fright break," that allowed patrons to receive a refund if they were too scared to stay for the climax of the film. Plot A mysterious woman named Emily (Arless) convinces the bellboy (Richard Rust) at a local hotel in Ventura, California to meet her later that day at a local justice of the peace to get married, offering him two thousand dollars in compensation.

Miriam also confesses to Warren good news of her own, that she is engaged to be married to her boyfriend. That evening, Emily breaks into Miriam's flower shop and wrecks the store. She is interrupted by Miriam's boyfriend, who comes to the store because he did not know that Miriam had left early that evening. Miriam and her boyfriend arrive at Warren's house the next day to visit Helga and confront Emily. Helga frantically tries to communicate with Miriam, who later finds out from Warren that Emily
