Quinn & Costa Thriller

An edgy female police detective... An ambitious FBI special agent... A ticking-clock investigation... Together they are at the center of a search for a diabolical serial killer. The bond they forge in this crucible sets the stage for high-stakes suspense. Detective Kara Quinn, on leave from the LAPD, is visiting her hometown of Liberty Lake when she comes upon the mutilated body of a young nurse during an early morning jog. The manner of death is brutal and ritualistic. Meanwhile in DC, FBI special agent in charge Mathias Costa is staffing his newly minted Mobile Response Team. One of his first recruits is the brilliant forensic psychiatrist Catherine Jones. Word reaches Matt that the Liberty Lake murder is likely the work of the Triple Killer-it will be the first case for the MRT. Jones wrote the only profile on this brutal killer but is reluctant to join the unit, shaken by her sister's recent murder. Only Catherine holds the key to the killer's obsessive pattern-three murder victims, three deep slashes, killed three days apart, each cycle starting on March 3, then a three-year hiatus before he strikes again. This time they have a chance to stop him before he claims another victim... But only if they can figure out who he is and where he is hiding. The stakes are higher than ever before, because if they fail, one of their own will be next.
