The latest fiendishly twisty mystery from the Richard and Judy NUMBER ONE bestseller Louise Douglas ✨ Perfect for fans of Eve Chase and Lucinda Riley. 📚

Twenty-five years ago, two-year-old Evie Albert disappeared without a trace from the Brittany seaside town of Morranez.

So, when a stranger called Nicole Stevenson walks into the offices of Touissants Detective Agency declaring herself the missing girl, Mila Shepherd and her colleague Carter Jackson are suspicious. They are inclined to agree with Nicole’s sisters Imogen and Charlotte, that for whatever reason, Nicole is a fantasist looking for attention.

But as Mila and Carter reopen the case of the missing toddler, a twisting tale of misdirection, a secret society and a forgotten mother slowly unfolds. Is it possible that Nicole really is Evie and how does the case link with the mysterious death of Mila’s sister Sophie and her husband Charlie?

Someone is desperate to protect the truth and as Nicole’s health falters and leads vanish into thin air, Mila faces a dilemma – risk everything or walk away from the case before it’s too late.

Louise Douglas is back in the Breton town of Morranez with a masterclass in page-turning plotting and unforgettable characters.
