Autumn's Riddle

Still waters run deep. And deadly.
Since joining the FBI Behavioral Analysis Unit, Special Agent Autumn Trent has watched her team disintegrate. A longtime agent was shot dead by his own partner, who later died by suicide. Two transferred, her best friend switched careers, and then her boss/boyfriend was blown up before her eyes. She’s one of the last left standing, barely holding on beneath the crushing weight of her grief.

But she’s still here. And she has a job to do.

A young woman has been found strangled at a mini-golf course, her head submerged in the castle moat. Her death mirrors two others within the last month. Each victim was young, blond, blue-eyed, and carefully positioned in eerily similar scenes. Three identical murders leave no room for coincidence.

This is the work of a serial killer. Killing unsuspecting women is child’s play to him.

As Autumn scrambles to decipher his twisted motives, she faces an even darker threat. The same ruthless adversary who tore her life apart by murdering her boyfriend has Autumn in their crosshairs. They’ll stop at nothing until she, too, has fallen.

Autumn’s Riddle, the fifth book in Mary Stone’s bestselling Autumn Trent Series, gives “water hazard” a whole new meaning.
