Death & Depravity — Arthur Cole; Nigel Williams

Book 3 in the Terry McGuire thrillers. A young man is found dead from an overdose in a secluded wood. A young woman with a false name is found dead from an overdose in an office toilet. Enquiries suggest the dead woman may be part of an illegal human trafficking network? DCI Terry McGuire believes a rogue batch of pure heroin is on the streets and a race is on to catch the supplier before more die, but a cold case and a flasher continues to haunt him.
