In the hushed halls of the British Library Reading Room, a sanctuary of knowledge hides a chilling secret. When an elderly professor is found murdered amidst at his desk, the scholarly calm of the Reading Room is shattered. Enter Mrs. Craggs, a humble charwoman with a sharp eye and a knack for uncovering truths others overlook. Overlooked herself by a world of scholars and "whizzers," she carries a quiet determination that surprises everyone—even herself. When Mrs. Craggs stumbles upon the crime, she finds herself drawn into a labyrinth of smooth-talking ambition and deceit. With the authorities sceptical and the suspect eager to cast blame elsewhere, can the stakes grow higher? Can Mrs. Craggs, armed with little more than her mp and her working-class common sense, expose the murderer before the wrong person is condemned? Learn more about your ad choices.
