But the murder of her best friend forces Bridge to go undercover inside a top secret military project, to root out a mole — where she uncovers a terrorist plot that threatens everything she has left to live for.

“A crackling fuse-wire of a book... Possibly the definitive espionage thriller of the early 21st century.”

Phil London is an ex-cop — and a psychic. He used to work for Section Five, a clandestine British paranormal police force, until his wife's suicide drove him to leave.

Realising his past as a 'Fiver' is the key to his survival, Phil fights for his life and sanity... down in London's subterranean frightening curves.

“A smart and viciously funny debut... Deftly plays on our fear of the unknown.”

But the job is not what it seems — soon the wizard has disappeared, the dignitary is dying, and Nicco is on the run...
