There is a terrific little bookstore in the closest major metropolis--I live in a town of about 27,000 people, and love it!--that has a pretty decent selection of old paperbacks, including a bunch of ACE Double mysteries.
Anyway, it's gotten me excited about the old ACE line, particularly the mysteries. So in my enthusiasm here are the cover scans of the Robert Bloch novels--two novels and one short story collection actually--published by ACE.
It's worth noting that many are of the opinion that the ACE crime line is inferior to many of its contemporaries, which is probably true, but if Robert Bloch's name is on the book; buy it!
Spiderweb was published in 1954
Shooting Star was published in 1958.
Terror in the Night was the second book published with Shooting Star in 1958.
Robert Bloch is best known as a horror writer, but in his early career he wrote some terrific crime novels, including the titles above. His work is tight, thrilling, vivid, and very fun. Hard Case Crime republished Spiderweb and Shooting Star in a double format a few years ago--pick it up, it's very much worth the $7.99. Now if HCC would republish Terror in the Night with, say, a collection of David Goodis short stories; or maybe John D. shorts.
