In the quiet, remote landscape of the Cambridgeshire Fens, the past is never truly buried — and neither are its secrets.

Crawling slowly forward on his elbows and knees, a man makes his way through the suffocating darkness of a cramped space deep in the Fens.

He fumbles with his torch, desperate to escape the tunnel before his fear paralyses him.

But he is too slow to see his killer.

Fifty years later.

Journalist Philip Dryden is writing what he thinks is a run-of-the-mill story on an archaeological dig at a World War Two POW camp in the misty Fens. Until they find skeletal human remains trapped in an underground tunnel.

There are two things no one can explain: the bullet hole in the dead man’s forehead and the direction of the body.

The prisoner was crawling in, not out.

And then a second, more recent, body is discovered.

Old crimes have burst into the present — and suddenly Dryden’s run-of-the-mill story has become explosive.

An unputdownable crime mystery, laced with dark secrets and a protagonist who is as flawed as he is determined, perfect for fans of Joy Ellis, Caro Ramsay, Ann Cleeves, Elly Griffiths, LJ Ross or Jack Cartwright.
