For more than a year, Emil Winge has dedicated himself to capturing the diabolical Tycho Ceton, with the invaluable assistance of one-armed army veteran and watchman Jean Michael Cardell. Their mission is made more difficult by the ever-increasing paranoia gripping Sweden’s royal family, who fear that a bloody revolution is brewing. A letter with the names of the revolutionary conspirators is said to be in the possession of Anna Stina Knapp, a good friend to Cardell. Now, Anna is missing and Cardell is determined to find her before the secret police take her into custody. While Winge and Cardell fight for justice and for life, they find themselves caught between powerful enemies --- those who will do anything to maintain the status quo, and those who will only be satisfied with its total destruction.

Stockholm, 1794: A young nobleman, Eric Three Roses, languishes in a hospital as the rest of the city claims that he belongs in a madhouse. Riddled with guilt, he writes down the memories of his lost love --- his beautiful wife who died on their wedding night. The young woman’s mother also mourns her death and, desperate for justice, begs for help from the only person who will listen to her: Jean Mickel Cardell, the one-armed watchman. But she isn’t the only person seeking him out. Emil, younger brother to the brilliant lawyer and detective Cecil Winge, finds the watchman to demand his late brother’s pocket watch back. Instead, Cardell enlists Emil’s help to discover what really happened at the Three Roses estate that dreaded wedding night.

One morning in the autumn of 1793, watchman Mikel Cardell is awakened from his drunken slumber with reports of a body seen floating in the Larder, once a pristine lake on Stockholm’s Southern Isle, now a rancid bog. Efforts to identify the bizarrely mutilated corpse are entrusted to incorruptible lawyer Cecil Winge, who enlists Cardell’s help to solve the case. But time is short: Winge’s health is failing, the monarchy is in shambles, and whispered conspiracies and paranoia abound. Winge and Cardell become immersed in a brutal world of guttersnipes and thieves, mercenaries and madams.
