What now? Women? Cigarettes? Whiskey? All day long? Richard Ellwanger, freshly divorced from the police service, is puzzled about how to spend his time from now on. Then a job offer comes from far-off New York: A wealthy woman has died, and her sister and father accuse the grieving husband of being someone other than he claims to be. They hire Ellwanger for a private investigation. For him, this means not only entrusting his black-furred housemate Killmousky to the neighbors. It also means navigating a metropolis where he is uncomfortable with the language, the customs are foreign, and a possible murderer lives, whose personality increasingly fascinates the former commissioner. Sibylle Lewitscharoff takes on a genre that millions love with her: Killmousky is an exciting crime novel and at the same time a linguistic delight.
