The House Without a Key - Earl Derr Biggers
I love everything Charlie Chan, from the novels to the black-and-white movies with Warner Oland as Chan. I guess because I've seen the movies so many times, it was easy for me to read this book as if it were a movie; I mean that I was able to picture it all in my head, with Oland as Chan and, for some reason, Joan Plowright as Minerva Winterslip. The book was an easy read, and of couse, full of Chan's witticisms. Not only does he solve the mystery, but he also manages to help Aunt Minerva get over her superior attitude and prejudice. I really enjoyed this book.
