The Big Kill (1951) is Mickey Spillane's fifth novel featuring private investigator Mike Hammer.

Drinking at a seedy bar on a rainy night, Hammer notices a man come in with an infant.

The man, named Decker, cries as he kisses the infant, then walks out in the rain and is shot dead.

The driver of the getaway car runs over the man Hammer shot to ensure that he won't talk.

William pulled a robbery on Riverside Drive the same night prior to his murder by ex-con Arnold Basil, a stooge for Lou Grindle.
