George Carol Sims wrote dark and violent short stories under the name Paul Cain for Black Mask Magazine in the 1930s, and we have seven examples in "Seven Slayers," all as well written as they are grim. Cain's world was The City, always wrapped in darkness, either late at night or in the neap hours of the morning, an eternal dark night of the soul for those who had either lost their faith, or never had any. His characters are detectives, gangsters, rum runners, newspapermen, stoolies, guns for hire, drunks, floozies, and society dames who don't know they're floozies. The police, when they appear, are always on the outside looking in, waiting for the cunning and hard-hitting private eyes to plug those who need plugging, to sort out the guilty from the not-quite-as-guilty from the just-plain-stupid before moving in with handcuffs and body bags. Other stories written eight decades back have not aged too well, but these amorality tales manage quite well, helped along by crisp dialogue and a narrative voice like the staccato chatter of a Tommy Gun. Cain was conversant with underworld slang and used it often, but most of it will be familiar to readers of period crime novels or easily derived from context. Fans of crime noir and pulp fiction in general will enjoy this collection.
