PATTY AND JO, DETECTIVES

I have had this book face out in my office for years simply because I love the jacket—it's so fabulous. Who can resist jacket illustration from the 1950s and 60s?! An online search didn't turn up much about the author, Elsie Wright, or her Patty and Jo detective series. I wonder if it was ghost written by a collective author group, similar to how the Nancy Drew series was handled in order to publish so many books in such a short period. The halo effect around the twins is such a terrific touch!
