This thing of darkness
(Book)

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 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. 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. That's when they come for her.
