A hotel closed for the winter, a snowy night, our hero and a key begin this delightful mystery. As we soon learn, our hero looking only for solitude, isn't the only one with a key. Other colorful characters arrive one by one and Biggers' descriptions and snappy writing style promises a wonderful read. I just learned that Earl Derr Biggers wrote the Charlie Chan series. No wonder "Seven Keys to Baldpate'' is so good!
