London, 1817: a city glittering with wealth and rotting with secrets.

In the uneasy years after the Napoleonic Wars—before fingerprints, detectives, or organized policing—one man bears the burden of justice alone. Captain Winter, once a decorated soldier and now Whitehall's "special emissary," moves easily between the capital's extremes: the stately parlors where power is traded behind fans and smiles, and the shadowed alleys where danger has no name. Haunted by the battles he survived and the brutality he learned not to fear, Winter is a man shaped by violence yet bound by a private code he struggles to honor.

When a young woman of means is found murdered in a notorious district, Winter's pursuit of the truth pulls him into a tangle of loyalties and lies. A nobleman from his boyhood offers entrée into high society; a brilliant Jewish physician exposes clues the dead cannot voice; and Barbara Lightwood—Winter's former lover, clever, beautiful, and perilous in her own right—reenters his life with information he needs and secrets she will not share.

From candlelit drawing rooms to the city's darkest taverns, Winter follows the threads of a crime that reaches further than anyone dares admit. Each step forces him to confront the man the war made him—and the man he still hopes he might be.

A richly atmospheric mystery where desire, danger, and duty intersect, Winter's Season evokes a London on the brink of modern justice—and the solitary, battle-hardened investigator who walks its narrow line.
