Trixie Belden and the Mystery Off Old Telegraph Road-#20 in series

The lack of displays for the Art Fair are disappointing. Nick Roberts, club head, tells Trixie and Honey that the club does not have money for more displays. Eager to help, the Bob-Whites get into the idea of a bike-a-thon. Trixie asks for Nick's help; however, Nick disagrees and tries to convince Trixie not to have the event. With or without Nick's help, Trixie proceeds with her plans. Trouble follows, and the bike-a-thon may be canceled. Trixie is determined to investigate to ensure that her plans for the fundraiser are successful.
