The Strawberry Strangler. Alaric Teagan Files, #2

Some murders are personal. Some killers wear an all-too-familiar face. The body of a teenage runaway wash out on the bank of the Chicago River. Detectives Rory Forrester and Carmen Morales are on the case. Someone is targeting young prostitutes. Girls who are desperate for money, who sell their bodies to bankroll drug addictions. A mysterious request from his sister Giselle calls True Crime Novelist Alaric Teagan back to Chicago.
He hasn't been home in six years. Haunted by a past that sleeps uneasily, Alaric must navigate his own ghosts while he assists the police. Together they traverse a web of deceit and obsession, where the truth hides behind a mirror darkly.
