When bodies burn without explanation, dark rituals may be to blame.

"Do you believe in spontaneous human combustion?" Detective Inspector Keith Tremayne asked.

When a series of mysterious deaths rock the quiet countryside, DI Tremayne and Sergeant Clare Yarwood find themselves investigating the impossible—bodies burned from the inside out, with no evidence of accelerant or external flame.

Tremayne—a man more comfortable with cigarettes, beer, and racing forms than books—must now venture into the ancient world of pagan rituals and occult practices. His practical, no-nonsense approach clashes with forces that defy rational explanation.

As the body count rises, the investigative duo discovers a sinister cult operating in the shadows. What began as a puzzling case quickly becomes a dangerous battle against those who worship death and summon powers beyond mortal understanding.

A gripping British police procedural where the supernatural and criminal investigation collides.
