What do You think about Mystery Of The Flying Express (1941)?
The classic boy detectives by Frank Dixon--I read ALL of them in my younger years, one I ran out of Nancy Drew books. The Hardy Boys are brother amateur detectives, aspiring to follow in their famous father's footsteps.The two boys live in the fictional city of Bayport (on Barmet Bay) with their famous father, Fenton Hardy, a private detective formerly with the New York Police Department, their mother Laura Hardy (erroneously called Mildred in The Flying Express), and their Aunt Gertrude, a character often used for comic relief.

I really enjoyed reading a book where siblings worked together to accomplish something good. No sibling rivalry, none of the "go away me and my friends are doing this." And the care and respect they show towards their parents and other adults in their life is simply remarkable. Good sound examples overall.Of course my copy is from the 1940's so there may be some differences between my copy and the newer updated versions. Anyway, although its not my typical reading fare I really did enjoy it and as long as there are old copies of this series around I wouldn't mind having them in my library.
