Mark Doyle and Shadows Of The Crown

Mark Doyle didn't want to be a ghost again. After four quiet years in retirement, the former MI6 operative is dragged back into the shadows when a British attaché vanishes in Berlin-leaving behind a trail of impossible clues, doctored photographs, and a name Britain buried in its darkest files. But Doyle's return awakens more than old instincts. It awakens enemies. Someone inside the British government has issued a termination order-against him.
Every step he takes uncovers deeper lies: covert kill-teams, erased operations, and a secret organisation older than MI6 itself. an organisation he may have unknowingly founded, and one that wants him wiped from history. From Berlin's frozen checkpoints to Paris's hidden archives, from Whitehall's sealed vaults to a nightmare buried beneath the cliffs of Cyprus, Mark Doyle races to uncover a truth powerful enough to burn the Crown to its foundations.
Betrayed by his own government. Hunted by Spectre Unit. Haunted by the woman he loved and the man who stole everything from him. And at the centre of it all-a phrase he cannot remember, and a weapon he never knew he carried. The past is reaching for him. The future depends on him. And Book One ends with a choice that will shatter everything. A gripping 1960s espionage thriller packed with twists, betrayals, and a cliffhanger that ignites the explosive four-book saga.
