This Thing of Darkness

A marine engineer who tumbles off a cliff path on a windy night. A burglary where everything taken was returned by the thief. The suicide of a man in love with life. An accident, a mystery, an unexplained tragedy. And nothing at all to connect them. Until, that is, Detective Constable Fiona Griffiths, searching for something - anything - to take her mind off the tedious job of evidence-cataloguing she's been assigned to, starts to wonder if all three incidents are not quite what they seem.

It could just be her imagination. After all, she'd be the first to admit that she isn't exactly in the prime of psychological health right now, the darkness she's held at bay ever since she joined the police force now lapping dangerously at her door. But something tells her there are invisible threads linking the crimes, and as she investigates further, she starts to see the outlines of a conspiracy so unlikely and on such a vast scale, that it takes her breath away. And that's when they come for her.
