Crime School — Carol O'Connell

Detective Kathleen Mallory recognized the dead call girl. It was someone from her past, a woman who protected her on the streets of New York--and who betrayed her. Mallory also recognized the crime scene: victim hanging, hair in mouth, fire burning. It happened twenty-one years ago, when Mallory was a child. Now--whether it's the work of a copycat killer or a serial murderer--it has happened again.
