A Snowball's Chance in Hell (DCI Logan Book 9), J D Kirk

Which list are you on? When a young man is found frozen to death on a Highland street in mid-December, DCI Jack Logan initially puts it down to a Christmas night out gone tragically wrong. But, when a post mortem reveals something more sinister, Jack discovers he is dealing with a cold, calculating killer with a long line of victims, a talent for torture, and a perverse sense of justice. Half a decade ago, the press dubbed him 'The Iceman' - a twisted vigilante who successfully evaded capture for two years, before melting away into the night.

Now, The Iceman has come back. His naughty list is longer than ever.
