What Remains: David Raker Missing Persons #6

Colm Healy used to be a policeman until, haunted by the murder of a young mother and her two children, his life unravels. Then, left with nothing but the hunt for a killer, he disappears. That's when Missing Person's Investigator David Raker gets involved. Raker knows Healy; had tried to help him. But now, instead of getting Healy back on his feet he's got to find him. And it's a search that even Raker's long experience of the missing can prepare him for; a trail of darkness and deceit in which nothing is quite what it seems.
