The Final Cipher (The Last Message Trilogy)

One last code. One final choice.

Rumours say Lionel Gage is dead. The truth is far more dangerous.

When Maya Dalton receives a mysterious thumb drive labelled 'THE FINAL CIPHER, ' she and Alex are thrust back into the shadows of their past. The file is tied to 'Nightfall, ' the off-books MI5 programme that trained Alex Rennie-and it reveals a chilling truth: 'Nightfall' never ended. It evolved.

Their search leads to a forgotten Cold War island turned digital fortress, run by 'The Architects, ' the hidden founders of global surveillance. And now, they're ready to unleash OBSIDIAN, a sentient system that will control the world under the guise of security.

As a storm rages, Alex and Maya infiltrate the island, facing traps, betrayal, and a gut-wrenching dilemma: destroy OBSIDIAN and risk global collapse, or let it live-and watch freedom die. But Maya has one last move.

A final patch. A fading signal. A system undone.

The truth gets out. But the cost is everything.

The Last Cipher is a heart-pounding conclusion about power, privacy, and the price of choice in a connected world.

Stephen Bentley is an award-winning author. Of his first true crime novel, UNDERCOVER, screenwriter and novelist, writer of 'Julie' BBC Drama, Rob Gittins, said, "The fascinating and extraordinary inside story from the man who was actually there."

Of his later fiction works, British crime author, Pat MacDonald said, "I knew when I read the author's first book 'Undercover: Operation Julie' although non-fiction that he could make the transition to writing fiction; I was right. He has an ease of language that lends itself to storytelling; he tells it as if he was there in the plot and why shouldn't he having been an undercover cop in the real world? Not that Steve Regan is meant to be him, but having the experience means he can do whatever he wants with his fictional characters, and they will always be believable."

Like some other authors, his life experience is broad and unconventional. He spent 30 years in the legal system, first as a detective for 15 years then as barrister plying his trade as "a wig for hire" in London and the English provinces. He was a pioneering undercover cop on Operation Julie and as a barrister defended in trials involving murder, rape, drug importation, other serious crimes and defended soldiers at courts-martial.

He worked in a warehouse. Rode a big motorbike as a London courier. He drove big articulated trucks and taught how to drive them. He also worked as a hospital porter twice. He drove chilled delivery vans in London in the 1990s to fund his law degree and bar school studies. He spent the last two years of his working life driving plant and operating heavy filtration machinery for Europe's largest water company. His work mates soon recognised his advocacy skills and elected him as their shop steward.

He has now written over twenty books. Two of them have been optioned and in development; one as a TV drama series, and one as a drama doc.
