When a lamp on Westminster Bridge is ordered to go dark before its time, a messenger never makes it home.The city calls it an unfortunate accident: bad weather, bad luck, a faulty omnibus brake. But to Ada Harrow-bookkeeper, investigator, and reluctant public witness-the missing light and the missing hour belong on the same page.Drawn into the affairs of the new Committee of Hours, Ada and her partner Mercy Voss find themselves tracking a pattern that runs through ledgers, lamp routes and Parliamentary papers. A lamplighter is told to snuff early "as trial." A brake is "improved and adjusted" the day before it fails. A telegraph office is paid to move an hour on paper so that a powerful Programme looks punctual over a dead boy.Somewhere between the bridge and the committee room, time itself is being treated as elastic-and risk is being moved off contracts and onto ordinary people.As witnesses file through hearings and inquiries, Ada follows the trail in the only way she knows: receipts, minutes, contracts, small entries that refuse to balance. What begins as one fall on a foggy evening becomes a fight over who is allowed to decide when an hour begins, and whose lives are counted as incidental when "improvements" go wrong.The Snuffed Light of Death is the second Ada Harrow mystery, returning to a gas-lit London of omnibuses, telegraph wires and quietly dangerous paperwork. It can be read as a sequel to Receipts of the Dead or as a standalone novel.For readers who enjoy character-driven historical mysteries with a slow burn, sharp dialogue, and a moral puzzle at the heart of the crime, Ada Harrow's new case asks a simple question with unsettling answers: If an hour can be bought, sold, or moved, what happens to the people who have to live inside it?
