Recs if you like The Glass Key...

Based on the list/book published in 2006, general editor Peter Boxall.

This list includes works and authors that influenced the game as well as others with similar themes and writing.

A list featuring classic hardboiled detective capers—largely cynical novels (and a few story collections) hailing primarily from the 20’s-50’s, populated by quick thinking and hard drinking detectives, femme fatales, gangsters, murders, and periodic guns fights; where coffee is served late at night, and there is almost always an abundance of cigarette smoke…

Called "the definitive library of mystery fiction". Howard Haycraft originally published the list in 1941 in Murder for Pleasure. It was updated and broadened by Ellery Queen. This is the final revision, including books from 1748 to 1952.

These books are historically significant because of their influence on the development of crime fiction, however books from these times often contain bigoted and otherwise offensive content.

I haven't read them all, or even a high percentage. I'm trying to keep track of how many on this list I read.

I could only find a Spanish language version of A Case to Answer by Edgar Lustgarten.
