When a ten-year-old girl turns up on DCI Ryan’s doorstep to tell him she’s witnessed a murder, he has no idea he’s about to step into his most spellbinding case yet.

When you sell your soul, the devil gives no refunds...

When an old man is burned alive in a sleepy ex-mining village, Detective Chief Inspector Ryan is called in to investigate. He soon discovers that, beneath the facade of a close-knit community, the burn from decades-old betrayal still smoulders. When everyone had a motive, can he unravel the secrets of the past before the killer strikes again?

Borderlands
When the gods made man, they made a weapon...

Ryan's Christmas
DCI Ryan and his team of murder detectives are enjoying a festive season, until a freak snowstorm forces their car off the main road and into the remote heart of Northumberland. Their Christmas spirit is soon tested when they’re forced to find shelter inside England’s most haunted castle, where they’re the uninvited guests at a ‘Candlelit Ghost Hunt’. It’s all fun and games—until one of the guests is murdered.
