London, 1716. Revenge is a dish best served ice cold…

The city is caught in the vice-like grip of a savage winter. Even the Thames has frozen over. But for Jonas Flynt – thief, gambler, killer – the chilling elements are the least of his worries…

Justice Geoffrey Dumont has been found dead at the base of St Paul’s cathedral, and a young male sex-worker, Sam Yates, has been taken into custody for the murder. Yates denies all charges, claiming he had received a message to meet the judge at the exact time of death.

The young man is a friend of Belle St Clair, and she asks Flynt to look into the murder. Their probing leads them to possible government corruption, Jacobite plots, the horrors of Newgate prison, and a desperate showdown on the ice.
