Trust No One - is the number one rule of the Montgomery Agency. The MFA consists of the best profilers who once worked for the FBI. Handpicked by Dr. Mark Mackenrowe, these agents will assist him in hunting the most deadly serial killers in the world: The Slasher—an avenger who made the entire United States his personal dumping ground. At last, he crosses path with his unknown and unwarranted protégé—The Red Mask, one of the craftiest serial killers of all time. Join the chase as he leaves a trail of corpses from the French Rivera, London, Italy and Spain then finally to the United States. Only one elite team has the potential to stop not one but three high-profile serial killers. Without remorse, these hunters murdered freely for the last three decades without capture. Now the hunters become the hunted! Woven into this tapestry of murder and mayhem are secrets and scandals. Inside of it all, sensuous romances and a triple twisted love triangle threaten to unravel the solid foundation of the Mackenrowes.
