A Killing Night by Jonathon King [Fiction, epub/mobi/pdf] {G4mbl3R}

Book four of the bestselling Max Freeman mystery series: Max's investigation of a string of murders in south Florida leads him to the most shocking of suspects. After three young female bartenders were murdered in Miami and one went missing in Philadelphia, Freeman's ex-girlfriend Sherry Richards hires him to help with the case. Freeman grudgingly accepts the job, despite Sherry's insistence that a retired police officer who saved Freeman's life back in Philadelphia is the prime suspect. As Freeman returns to Philly to investigate, he must face his feelings of camaraderie for his former colleague, his affection for Sherry, and a resurgence of his own personal demons in order to solve the crime before the killer can strike again.
