I first read a book of this series when I was 6 and each time I was at the library I was searching for a new one. These books are detective stories lead by a young girl. Her name is Françoise but when she fights crime she is wearing a sort of superhero suit and a funny hat with a pompom on top. The stories are fun and filled with suspense, this way, I suppose, when a mum reads them to her kids she is a bit entertained as well. Since then, a TV show has been made out of it. I highly recommend any of the series.
