Hapless, pot-smoking private investigator Dave Randolph's latest investigation takes a turn for the unthinkable with a startling discovery: he is killing people in his sleep. Dave is a homicidal somnambulist, harbouring a nocturnal self responsible for a spree of gruesome vigilante killings which have left the Edinburgh authorities baffled and with no more evidence on the killer's identity than the mysterious insignia appearing in situ at each of the crime scenes; 'Dave Nocturne'. Nocturne's increasingly sloppy handiwork, however, soon leaves a trail of clues. Edinburgh Criminal Investigations Department are closing in on him and Randolph's former employer and long-term love rival is closing in on his wife. Unable to confess and condemn himself to a life without his wife and unborn child, Randolph is pitched into a frantic struggle to halt his nocturnal self's ever more wayward spree before his old foes on CID's Z-squad catch up with him. Nocturne, however, is inside his head, impervious to all attempts to stop him... "An enthralling read. Cunningham grips. An addictive concoction of realism and wit bound by an almighty dark twist."
