A secret, hidden inside a lie, concealed behind a deception. Twin eight-year-old brothers Devin and Archie Milner are staying with their grandmother for the weekend on the remote West Pennine Moors. They are beyond excited. Being there is always such a brilliant adventure, and this time it's going to be even better. They've been allowed to camp out on their own. After all, they're big boys now, they're miles from anywhere, far from danger, perfectly safe... So, when Devin is snatched in the middle of night, the family and the local community are left stunned and too terrified to even contemplate the abductor's motives. It's the first case for newly qualified detective Riley Strickland. Affected by a rare form of OCD, and with the investigation raking up his own personal demons, Riley senses that there is something else going on at the dark heart of the abduction. To get to a truth that has been hidden away for decades, he must face down prejudice, challenge police negligence and overcome deception at every turn. But someone out there is determined to keep all the secrets buried. And time is running out for Devin Milner.
