Quite possibly the greatest author to appear in the pages of Black Mask magazine-Dashiell Hammett-is finally included in the authorized Black Mask Library. Hammett's influential Continental Op series set the editorial tone for Black Mask and all of the authors who would follow Hammett in that magazine. This Volume 1 collects the first ten stories of the Op, including the first two installments bylined as "Peter Collinson," along with an all-new introduction by Bob Byrne.
