This is the third Mammoth comics volumes--the first two focusing on war & horror. Both of those earlier volumes were hampered, although not crippled, by the refusals of EC, DC, Marvel/Atlas & Warren to allow reprints of their stories (although Warren tales did appear in the War volume). However this volume focuses on crime, a genre neither DC or Marvel/Atlas did much of importance with, Warren only produced a few stories in (although they tended to be of quite high quality) and, in fact, an EC story does appear here.
With almost the entire field to choose from the quality of this volume is very high with an excellent 1934 Dashiell Hammett/Alex Raymond tale from Secret Agent X-9; two stories from Bernie Krigstein (including the very strange 'Blind Man's Bluff' which was his swansong to comics); obscure but high quality Alan Moore & Neil Gaiman tales (including Moore's epilogue to his graphic novel 'From Hell'); a great Max Collins/Terry Beatty Ms. Tree tale, a fine Johnny Craig story from EC, Jack Cole's classic 'Murder, Morphine And Me!', a fine Joe Simon/Jack Kirby bunko tale, some decent Euro crime tales making their North American debuts, Will Eisner's Spirit (although one might quibble why 'The Portier Fortune'--a good but not great Spirit tale appears, when such genuine noir greats like 'Black Alley', 'Ten Minutes' or 'Fox At Bay' were passed by), Jordi Bernet with a Torpedo tale, an Alex Toth classic, Charles Burns' El Boro and much, much more. In fact, the quality of this book is so high while the price is so low that it may well be the best comic anthology of the year for your dollar.
