Mord ist mein Geschäft, Liebling (Killing Is My Business, Honey) is a German comedy film directed by Sebastian Niemann [de].

As crazy as he is, he writes on a typewriter and sends a unique typescript to his publisher who is already about to have a huge press conference on this book.

She takes Ricardelli to Germany, where he asks his blind uncle Pepe (Bud Spencer) to make up some stories and to have them written down by a restaurant owner.

But now mafia boss Salvatore Marino (Günther Kaufmann) also believes Ricardelli was the unknown author and wants to have him killed.

Trying to achieve that he hires a bunch of killers including Ricardelli's old rival Helmut Münchinger (Christian Tramitz).
