I'm looking for good detective stories for my 7yo DS, either easy chapter books (about the same level as Beast Quest and Astrosaurs) that he can read to himself or harder ones that I can read to him. I saw the Whodunit Detective Agency series by Martin Widmark on Amazon, but they are newly published and don't have any reviews yet. Has anyone tried these? Or can anyone recommend any other good mystery books? Thanks very much.
Link to author's website The books are stuffed with puns, and the basic scenario is that the elder Diamond brother is the world's dimmest detective, and his smarter little brother saves the day. Six in the series; we loved them.
(Same author as Alex Rider for when he's a bit bigger. And he writes crime for TV and for adults too).
