Summoning the dead

"We have a dead child, and a crime scene that has been remarkably well kept for us." A young child lies mummified in a barrel.

His hands, cable-tied, appear to be locked in prayer.

As forensic officers remove the boy they are in for an even bigger shock -- he is not alone. With his near-fatal stabbing almost a memory, DI Bob Valentine is settling back into life on the force but he knows nothing will ever be the same.

Haunted by unearthly visions that appear like waking dreams, he soon understands he is being inducted into one of Scotland's darkest secrets. When the boy in the barrel is identified as a missing child from the 1980s, it re-opens a cold case that was previously thought unsolvable.

When further remains are unearthed, the facts point to a paedophile ring and a political conspiracy that leads all the way to the most hallowed corridors of power.
