A decorated World War I hero and the nation's most famous detective, Willi also is a Jew. Despite his elite status in the criminal police, he is disturbed by the direction Germany is taking. Working urgently to identify the dead woman and solve the murder, Willi finds his superiors diverting him at every turn, and is forced to waste precious time on a politically-sensitive missing person case. Colleagues seem to avoid him; a man on a streetcar stops him from reading a newspaper over his shoulder; he is uncomfortably aware of being watched. But he persists, and soon enters the dangerous Berlin underworld of debauched nightclubs, prostitutes with secrets to hide, and a hypnotist with troubling connections.
As he moves through darkness closer to the truth, Willi begins to understand that much more than the solution to a murder is at stake. What he discovers will mean that his life, the lives of his friends and family, and Germany itself will never be the same
The Sleepwalkers is a powerful, dramatic debut thriller of a nation's unstoppable corruption, featuring a good man trapped between his duty to serve and his grave doubts about what, and who, he serves.

Paris, 1933. A refugee with no papers, no legal status, and few resources, Willi Kraus lives in fear of deportation back to Nazi Germany. His reputation as a top sleuth however precedes him, and he's soon enlisted to work as a private eye-if under shady circumstances.
Despite his apparent good fortune he finds himself a stranger in a very strange land. France is gripped by a fog of disillusionment, anxious about the tides of fascism rising along her borders. Seduced by a sultry but troubled young French girl and befriended by France's most flamboyant financier, Willi finds himself unwittingly drawn into a murder mystery whose trail points towards the highest halls of power.
Without a badge, working alone, he gradually gets the impression he's being led into a maze. By whom and for what purpose? To escape this web of intrigue he must learn to navigate not only the grand salons of Paris but her seediest alleys and darkest canals, her smokiest nightclubs-a landscape as disorienting as a hall of mirrors, where sex, politics, money and love are often just tricks of the eye. . . in Paul Grossman's Brotherhood of Fear.
