Former US Marine, sometimes private investigator, oftentimes hit man for hire, Kellerman is as hard core as they come. Peppered into his life, Kellerman's closest friend from the Corps and sometimes backup man is gay, his business associate is a Cuban mobster in New York's Hell's Kitchen and his girlfriend is a cop. When the three college boys who raped and left a young girl for dead are found innocent on a technicality, the girl's father comes to Kellerman for justice. He gets it, Kellerman style. From first page to last, Kellerman's seedy world in Hell's Kitchen will leave you wanting more and Kellerman usually delivers with a dead body or two along the way. Checkmate is a hard core, action lover's delight.
