Belgrade Cipher

For readers of John le Carré, Mick Herron, and Daniel Silva.Four investigations. Four times the trail turned away from Belgrade at the exact moment it mattered. Marcus Vane has finally stopped asking who he is chasing and started asking a colder question: who has been steering him away — and why one city keeps falling into the blind spot of every case he has ever run.In Belgrade he finds not another operative but a coordinating hand: a node that has been quietly redirecting the investigation chain itself, deciding for years what he was allowed to find. To break it, he must do the one thing his whole career has trained him against — distrust the very pattern of his own success.The Belgrade Cipher is a taut, cerebral standalone spy thriller: atmospheric, morally complex, and built for a single sleepless sitting. Set in the world of the Marcus Vane series.No cliffhanger. No sequel to wait on. Just one complete, quietly devastating night of espionage.
