The Devil Comes to Bylands: A British Psychological Crime Thriller

By Jacqueline Beard

A British psychological crime thriller set in a luxury spa built on the ruins of a Victorian asylum, where a lockdown traps two private investigators with a killer. Locked-room suspense, medical menace and a setting with its own terrible history.

The Spa Promises Silence. The Asylum Beneath It Was Never Quiet.

Some places never forget. Some places never forgive.

The Bylands Spa Retreat sells serenity: five-star suites, scented pools and the promise of silence. Beneath its manicured grounds lie the ruins of an asylum where nightmares were routine and mercy was forbidden.

Private investigator Sean Tallis came for a weekend escape. His colleague Saskia Denman arrived uninvited and walked straight into a murder scene.

When a biohazard scare seals the retreat, Denman and Tallis realise the murder is only the beginning. The lockdown isn't containment. It's cover. Behind the sealed doors, someone is reviving the asylum's darkest experiments.

And they're not finished.

The Devil Comes to Bylands is an instalment in the Denman & Tallis Cotswold Crime Thrillers series, for readers who love locked-room mysteries, private investigator duos and settings that hide their own crimes. Perfect for fans of Tana French, Elly Griffiths and L.J. Ross.
