Dingo Towne, a local character, has died and instead of a regular will, he’s set a series of riddles, with the winner taking his fortune. Hired by Dingo’s daughter-in-law to try and solve the riddles, the boys have to compete with nasty English relatives, Skinny Norris and treasure hunters. A very sturdy mystery, well constructed with clever clues, this is a cracking adventure, with good action, nifty set pieces (the river boat and climax especially) and a lot of different locations in and around Rocky Beach. It also has a very winning character in Billy Towne, Dingo’s 8 year old nephew, who is well written and good fun. One of the series highlights, very much recommended.
