Believe No One

Fennimore & Simms book 2

Believe No One by A. D. Garrett - UK book cover

DCI Kate Simms is on assignment in the United States with St Louis PD, reviewing cold cases, sharing expertise. Forensic expert Professor Nick Fennimore follows her, keen to pick up where they left off after their last case – but the last thing Simms needs is Fennimore complicating her life…

A call for help from a rural sheriff’s deputy takes Fennimore to Oklahoma; a welcome distraction, until he discovers the circumstances – a mother is dead, her child gone – and they’re not the only ones. How many more young mothers have been killed, how many children are unaccounted for? Back in St Louis, the cold case team discovers a pattern: victims – all single moms – dumped along a 600 mile stretch of Interstate-44. The Oklahoma and St Louis investigations converge, uncovering serial murders across two continents and two decades.

Meanwhile, nine-year-old Red, adventuring in Oklahoma’s backwoods, has no clue that he and his mom are in the killer’s sights – but soon the race is on to find a serial killer and save the boy.

‘The best book I have read in years.’ Mo Hayder

Like their detecting duo, A. D. Garrett is a writing duo – Margaret Murphy, author of nine previous psychological thrillers and Professor Dave Barclay, himself a forensic scientist. They pull all these plot threads together into a gripping read that still leaves unanswered questions – about Josh’s shady past and Suzie’s fate. I can’t wait for more. Bookloons

I Love a Mystery newsletter: ‘The author never skimps on any of the(se) characters — each is well drawn no matter how much or little time he or she spends in the story.
