The Exphoria Code

“Could help to redefine the espionage thriller as a literary genre... In Brigitte Sharp he has created the perfect, if reluctant, spy for this troubled modern age.”
Shots Mag

“Johnston is a talent to look out for and this, his latest entry into the world of espionage, is a treat.”
Anthony Horowitz

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


MI6 cyber-analyst Brigitte Sharp has spent three years deskbound and in therapy, traumatised after her very first field op went badly wrong and caused the death of a fellow officer. Despite her boss' encouragement, Bridge isn't ready to go back in the field...

...Until her best friend is murdered, seemingly in connection to a series of strange internet posts. Bridge is forced to go undercover inside a top secret military project to root out a mole — who may also be her friend's killer.

But the truth behind the Exphoria code is worse than anyone imagined, and soon Bridge is on the run, desperate and alone, as a terrorist plot unfolds and threatens everything she has left to live for.

THE EXPHORIA CODE is my first mainstream novel, and begins the Brigitte Sharp series of cutting-edge espionage thrillers. It's published by Lightning Books.
