Five books. One complete story. Everything you need to understand why the Retired Assassins' Club doesn't stay retired. This collection brings together the full first arc of Sam Chase's acclaimed spy thriller series - from the free prequel that started it all to the explosive finale that closes the chapter on the Agency's most dangerous secret. Included in this collection, in reading order: THE SCHOLAR (Book 1) Someone is running covert operations under Gabriel's old Agency designation, using his reputation to pull retired operatives into the open. He has days to shut it down before the people he's spent his career protecting run out of time. THE WIDOW (Book 2) Serena Marchand has rebuilt her life in the Roussillon under a new name. When the man she spared six years ago finds her new address - and arrives not to threaten her but to pay a debt - what he brings is more dangerous than any weapon. THE GHOST (Book 3) Maya Ramirez has been in the Amazon for four years, building a sanctuary and mapping every approach. She knows someone is coming eleven days before Gabriel's warning arrives. She's been getting ready. THE LOCKSMITH (Book 4) Ivan Petrov repairs antique locks on the Portuguese coast. When a young woman walks in with a key her dead father left behind - an Agency-made key that opens a twenty-five-year-old archive - the men who want that archive buried are already outside. THE CONDUCTOR (Book 5) Luca Moretti owns a jazz club in Naples and reads rooms the way other people read music. He's known for six weeks that the Sable programme's operational director is coming for the cipher matrix that will either verify - or suppress - everything the team has uncovered.
