Chuck Finn

Charles Finn, just arrived in Tingalla with his family from Canada, meets the ghosts on the Tingalla Rose, a paddlesteamer undergoing renovation by Sarah's father. Charles forms an uneasy alliance with Sarah after a mutual run-in with "Tiny" Maloney and the Bandits.

When Chuck, Sarah and David independently promote the Tingalla Rose they end up with three new crew members. Two crooks try to rip off the enterprise by stealing their own opals, but end up with a Diamond Collar.

Mrs. Littlemore, determined to put the Tingalla Rose out of action, arranges for an inspector to check out the riverboat. The gang have to cater to the whims of Mr Smith, Mr Jones and Miss Brown as any of them could be the inspector.

The gang find a treasure map with clues written in poetry, in an old box in the hold and discover it belonged to the bushranger Captain Candlelight, Fingers' once-time lover. When the Bandits get hold of it the race is on to locate the treasure.

When Chuck's fundraising ideas don't work, he suggests putting on a show on the boat to raise money. Mrs Littlemore recruits the Bandits to steal the gang's costumes and lure them into a trap just before the performance. Hamish & Buddy save the day.

Chuck complains about parents just as Glitch, a descendant of Fingers from 40th century, swaps places with her. She arranges it so that kids and adults swap places but when everything's not as easy as it first seemed, they plot to oust Glitch.
