Learn moreTrixie’s summer is going to be sooo boring with her two older brothers away at camp. But then a millionaire’s daughter moves into the next-door mansion, an old miser hides a fortune in his decrepit house, and a runaway kid starts hiding out in Sleepyside!
JULIE CAMPBELL, in the 1940s, was running her own literary agency when Western Publishing put out a call for talented authors to write mystery series for kids. Julie proposed the Trixie Belden series and wrote the first six titles herself. She also started the Ginnie Gordon series and wrote several Cherry Ames books. Julie Campbell died in 1999.
