The folks at Crime Reads have created a list of great amateur sleuth series for readers over twenty. Like Nancy Drew, these mysteries focus on keen intuition, loyal (or seemingly loyal) friends & a sometimes misplaced confidence. But remember, you are never too old to sit back, relax and enjoy a Nancy Drew mystery. I’d recommend The Mystery of the Tolling Bell or The Secret of the Old Clock. They’re two of my favourites.
