I, the Jury is the 1947 debut novel of American crime fiction writer Mickey Spillane, the first work to feature private investigator Mike Hammer.

Losing his arm rendered Jack unfit for police work, so he put his experience to use by investigating insurance fraud.

Prior to his death, Jack had fallen in love with Myrna Devlin when he stopped her from committing suicide by jumping from a bridge.

Williams asked Dr. Charlotte Manning, a young, beautiful, blonde, and well-to-do psychiatrist, to admit Myrna to her clinic for psychotherapy.

Taking time out from his investigation on a Saturday morning, Hammer picks up Myrna Devlin and gives her a lift to an estate in the country, owned by the lovely Bellamy twins, for a gigantic all-day party.

After an unsuccessful attempt at playing tennis himself, Hammer gets rid of his sleep deficit by spending all day in his room, fast asleep, with "old junior" — his gun — close to him.

After a four-picture contract was signed with Spillane, the movie was filmed, in 3-D, featuring Biff Elliot (as Mike Hammer), Preston Foster and Peggie Castle.
