Club Howson shared scriptwriting duties fairly equally with Peter Homewood and Max Bartlett, for Adventure Island Howson wrote most of the scripts, with others contributed by Peter Homewood. Howson also wrote four illustrated storybooks based on the show which were given a single limited print run. They quickly sold out and are now extremely rare. 1967–68 Nancy Cato was Adventure Island's first host during 1967–68. Cato had been forced to leave The Magic Circle Club dramatically in 1966 after an on-set accident, and she joined Adventure Island after her recovery. Each show would begin with Cato in an enchanted wood (one of the show's few direct similarities with The Magic Circle Club). In early episodes, Nancy would sit down behind a tree-stump lectern on which was poised a magic book, open the book and begin to read the story. The story would be based on a place called Adventure Island and the residents of its town of Diddley-Dum-Diddley, and viewers would see the story played out by the characters themselves. In later episodes, Nancy would begin the show by bantering with puppets Gussie Galah, Crispian Cockatoo and Matilda Mouse, then read from the book. At the conclusion of each chapter, Nancy would talk to a cat puppet, which was named Samson in a viewer competition early in the show's run. 1969-72 Sue Donovan took over the hosting role in 1969 after Cato's unexpected departure. The show's basic structure remained, but each episode instead began with a conversation with a talking house (Mister House, later named Serendipity House in a viewer competition) voiced by Jack Manuel and sometimes Ernie Bourne). Sue would then walk into the house where she would ad-lib with Crispian Cockatoo and Gracie Galah on Mondays, Wednesdays and Fridays, and with Maxie Mouse (Ernie Bourne) and a vertical waveform called Chi on Tuesdays and Thursdays. A chime would sound to indicate it was time for Sue to read the book. Each show would close with Sue talking to Samson the cat, but on Fridays she would click her fingers and magically transport herself to Diddley-Dum-Diddley for a sitdown chat and a cup of tea with all the characters. Premise The show was highly moralistic with a strong "good over evil" motif in every story. The scripted part of the show—a story serialised over five days, Monday to Friday—usually involved the inhabitants of Diddley-Dum-Diddley being set upon or tricked
