Think you know the person you’re married to? Think again. The Glasgow Fair weekend was usually the busiest of the year for the Serious Crime Division. But by the Sunday morning, it appeared to have gone off without a major hitch. Then DCI Dani Bevan received a call from one of her team. A middle-aged man had gone missing from his home in Giffnock. Dani didn’t take the case too seriously, until it turned out that the uncle of her friend, DC Andy Calder, disappeared under identical circumstances a decade before.

Five walkers set out to climb Ben Lomond on a fine October day. Within hours the weather has taken a turn for the worst. The group find themselves lost on the mountain. Two of the climbers manage to make it back down and call for help. The following day a body is found. One of the female climbers has been strangled, and another man is missing without a trace. DCI Dani Bevan is called to the Loch Lomond town of Ardyle to lead the case.

DCI Dani Bevan finds herself dragged into the disturbing case of Eric Fisher, a man accused of slaughtering his own family in a case of domestic homicide. But when a spate of violent burglaries breaks out in the area, while Fisher is on remand, Dani wonders if the man’s claims of innocence are as crazy as they first thought. The DCI quickly becomes caught up in a race against time to stop a terrifying serial killer, who appears to be one step ahead of Dani’s every move.

St Andrews, Scotland.

The charred remains of an elderly woman are discovered in a burned-out gamekeeper's cottage, hidden away in woodland to the west of Edinburgh. Clearly no accidental fire, Detective Inspector Tony McLean suspects that neither is this simply a grim arson attack. There is far more to the victim than her humble surroundings might suggest, and something ritualistic to her horrific murder. Nor will it be the only case of death by fire that Tony and his team will be faced with. This is only the beginning, and with such evil clouding the air, Tony begins to wonder what else will burn....
