Delirium by J.F.Penn“Those who the Gods wish to destroy, they first make mad.”

LONDON. When a prominent psychiatrist is found murdered in the old hospital of Bedlam, Detective Sergeant Jamie Brooke finds herself investigating the history of madness to fathom the motive. Blake Daniel, a reluctant psychic, helps her to research the case, only to discover that his own family are entwined with the shadowy forces that seek to control the minds of the mad.

As the body count rises, and those she loves are threatened, Jamie discovers that the tendrils of conspiracy wind themselves into the very heart of the British government. Can she stop the killer before madness takes its ultimate revenge?

A thriller with an edge of the supernatural, Delirium is a story of love for family, revenge for injustice and the question of whether we all sit on the spectrum of madness somewhere.

DELIRIUM is available from Amazon, Kobo and the author’s website.
