Come Fill the Cup is a 1952 novel written by journalist-turned-author Harlan Ware. The book falls squarely into the crime drama, noir, and realistic gritty fiction genres, blending a detailed look at mid-century newspaper journalism and the harsh realities of alcoholism with a fast-paced underworld crime plot. 

The book is famously known for its 1951 film adaptation starring James Cagney as the lead protagonist (interestingly, the movie was released just ahead of the book's official publication).
