A.D. Garrett is the pseudonym for prize-winning novelist Margaret Murphy working in consultation with policing and forensics expert, Helen Pepper. Margaret Murphy has published nine internationally acclaimed psychological thrillers under her own name – both stand-alone and police series. She is Writing Fellow and Reading Round Lector for the Royal Literary Fund, a past Chair of the British Crime Writers Association (CWA), and founder of Murder Squad. A CWA Short Story Dagger winner, her novels have been shortlisted several awards. Her lifelong passion for science is reflected in her painstaking research. In 2013, writing as A.D. Garrett, Margaret began a new forensic series, featuring Professor Nick Fennimore and DCI Kate Simms. Everyone Lies, which Ann Cleeves rated ‘thriller writing at its best’, was a bestseller, and both Everyone Lies and the sequel, Believe No One, garnered coveted starred reviews from Publishers’ Weekly. Jeffery Deaver commented, ‘A.D. Garrett has done for Manchester what The Wire did for Baltimore. And Simms and Fennimore are complex, compelling, and just plain marvellous.’ Truth Will Out, the third in the series, will be published in November 2016. Helen Pepper is a Senior Lecturer in Policing at Teesside University in the UK. She has been an analyst, Forensic Scientist, Scene of Crime Officer, CSI, and Crime Scene Manager. As a Crime Scene Investigator, she examined over 3000 crime scenes, ranging from thefts and fires to rapes and murders. Later, as Crime Scene Manager, she supervised CSIs in over 50 major incidents. She is a member of the Chartered Society of Forensic Sciences, and has a wealth of experience in the investigation of all crime types, from simple thefts to murders and terrorism. An author in her own right, Helen has co-authored, as well as contributed to, professional policing texts. Her expertise is in great demand with crime writers: she is a judge for the CWA’s Non-Fiction Dagger award, and is Forensic Consultant on both the Vera and Shetland TV series.
