Calle Claus (*1971) lives in Hamburg. He is illustrating and writing comics. His first Die drei ???-Fall has been the "Gespensterschloss" underneath the blanket with goosebumps at a sleepover at a school friend's. Before the Die drei ??? graphic novels, published by KOSMOS Verlag, he already wrote many stories for kids and teens, from radio dramas about soccer teams to comics about unicorns.
