Everyone Lies has proved a hit in hardback with both authors appearing on BBC TV. This fast-paced action crime thriller teams science, forensics and plot.

This is thriller writing at its best: prose that's startling in its pace and clarity, characters who come to life immediately and the bonus of knowing that all the forensic details are entirely accurate. -- Ann Cleeves A throat-clutcher from page one. Everyone Lies is a pulse pounding thriller, which weaves expertly between evil on the streets and the dark side of police department politics. A. D. Garrett has done for Manchester what The Wire did for Baltimore. And our central characters, Simms and Fennimore, are complex, compelling and just plain marvellous. -- Jeffery Deaver Awesome...What A. D. Garrett doesn't understand about forensic science and its applications isn't worth knowing. Ditto characterisation, plot and pace. A sterling debut. -- Mo Hayder A collaboration between a thriller writer and a forensic scientist produces a police procedural which promises well for the future of the partnership and provides a good read. Bookbag A marriage made in crime fiction heaven. CrimeFictionLover
