Donald Duck & Co #3/1996

In "Gjørmehavet," Professor Punktum is arrested on suspicion of smuggling rare birds to Andeby, prompting his daughter to enlist Mickey and Scrooge to clear his name. The trio journeys to the remote Søndre Basill, where secrets and strange bird behavior may hold the key to the mystery. Written by John Kane, Jack Sutter, and Harald Dyrkorn, with art and inks by Ignacio Calvet, this 1996 adventure blends suspense and humor in a story that's as much about loyalty as it is about solving a puzzling case.
