Seven Keys to Baldpate - Earl Derr Biggers
Up till this one, I've thoroughly enjoyed everything I've read from Earl Derr Biggers, including the works that don't include Charlie Chan. This was just didn't work for me. It seemed forced, almost like Biggers was trying to write like someone else. He's still one of my favorite authors, but I can't honestly give this one more than two or 2.5 stars.
