"[2] Moore's protagonist, Vincent Calvino, half-Jewish and half-Italian, is an ex-lawyer from New York, who, under ambiguous circumstances, gave up law practice and became a private eye in Bangkok.
Calvino has often been likened to classic hardboiled detective characters like Raymond Chandler's Philip Marlowe, Dashiell Hammett's Sam Spade, and Mickey Spillane's Mike Hammer.
"The hard-bitten worldview and the cynical, bruised idealism of his battered hero [Vincent Calvino] is right out of Chandler," wrote Kevin Burton Smith in January Magazine.
Douglas Fetherling said "Moore is a genuine novelist who just happens to employ the conventions of the thriller genre, that his real interests are believable human behavior and way cultures cross-pollinate and sometimes crash.
Moore's Vincent Calvino Private Eye series is a hardboiled crime fiction in the Western tradition reinvented in an exotic but realistic Southeast Asia.
