Query: O, Jerusalem

Laurie King keeps the reader guessing until the last page with this intelligent, highly suspenseful fifth mystery in her series involving Sherlock Holmes and Mary Russell. The reader gets an education along the way, dipping into history, archaeology, Arab customs and criminology. Who would have thought anyone could reinvent Holmes and give him a female companion while remaining so true to Conan Doyle's original man? I will give this book as gifts to many friends, then await their excited reviews. Tell King to keep the Mary Russell books coming!
