A Hidden Enemy
"Rules? They left those behind a long time ago."
They don't exist on paper. That's exactly why MI5 needs them.
A disgraced Russian intelligence officer resurfaces in the UK with a single objective: steal the guidance data for a next-generation missile system. Tom Kessler's team is brought in off the books. Unofficial. Untraceable. Completely expendable if it goes wrong.
It goes wrong.
A brutal attack leaves the team fractured. Moscow escalates, sending a GRU colonel whose presence means this operation is no longer deniable and failure is no longer survivable. Tom's team must turn a compromised insider, track a seasoned illegal, and hold themselves together long enough to execute a high-risk deception, with no margin for error and no backup.
There is no official version of events.
There are only consequences.
A Hidden Enemy is a tightly plotted British espionage thriller built on real intelligence tradecraft, where the threat is state-level, the stakes are global, and the team fighting it officially doesn't exist.

I write British crime and intelligence fiction with a procedural edge. The detail comes from having lived the work rather than researched it.
Before writing came service in the Royal Air Force, then nine years as a detective on the Surrey Drug Squad: surveillance both conventional and electronic, criminal intelligence, informant handling and undercover operations. The characters are complex and the operations are grounded, because I've done the work. The tension is never for show.
The Tom Kessler series now runs to five novels, beginning with A Detective's Dilemma, which introduces Detective Constable Tom Kessler on a Surrey drug squad. The series moves from street-level policing into intelligence and geopolitical territory, and a sixth book is in progress. The first four titles are published in Spanish, Brazilian Portuguese, Italian and German.
British thrillers for readers of Stephen Leather and Neil Lancaster.
Whether it's the patience of a long surveillance shift or the urgency of a high-stakes bust, I aim to capture the nuance of the work and the lives behind it.
When I'm not writing, you'll find me walking the countryside, fly fishing, or watching rugby with a pint in my hand. It's a slower pace than the one I used to live, but the stories haven't stopped.
