Deckname Quarry

Quarry was created in 1971 while author Max Allan Collins was a student at the Iowa Writer's Workshop, and later appeared in four novels between 1976 and 1977, with a 5th (and supposedly final) book appearing in 1987. However, in 2006 publisher Charles Ardai of Hard Case Crime appealed to Collins to write a another Quarry novel, which eventually lead to a new series of books featuring the character. As of 2016, HCC has published 7 additional books about the hit man.
