London, 1872. A widow inherits a workshop. The clock is still ticking. Someone has wound it since her husband died.
George Hartwell, master clockmaker of Clerkenwell, is found dead in his workshop on a cold March night, struck down by persons unknown between nine and eleven o'clock. The coroner calls it murder. Detective Inspector Whitmore calls it an open investigation. And Constance Hartwell, who has spent eleven years quietly learning her husband's trade from the inside out, calls it the beginning of the most important work she has ever done.
George left her everything: the workshop, the tools, the commissions, the customers, and the secrets. There are more secrets than she expected. Three fine movements in the stock with no acquisition records. A tin box of coded correspondence hidden behind the oil cabinet. A set of engraving punches that have been making a mark she does not recognize on movements she cannot trace. And a man named Aldous Fenn who arrived two days after the funeral to collect property he claims is his, with an unnamed companion who looked at the workshop's contents with the precise attention of someone who has been there before.
Constance knows clocks. She knows how to read a mechanism from its symptoms back to its fault, how to identify the point of failure from the evidence of the running parts, how to reassemble a complex system once the fault has been found. She applies these skills to the investigation with the same patience and precision she brings to a fine escapement, working through the Clockmakers' Company's careful silences, a rival's reluctant confession, a Swiss manufacturer's damning documentation, and the specific geometry of profit and deception that someone decided was worth a man's life.
Set against the competitive anxieties of the Victorian precision instrument trade, the real history of the Clockmakers' Company, and the specific legal landscape of the 1870s when a widow's right to run a business was new enough to require demonstration, The Clockmaker's Widow is a novel about what a capable woman can accomplish when the world mistakes her mourning for helplessness.
The clock kept ticking. So did she.
