Query: Intellegent and Funny Historical Mystery

Oakley Hall is at his best with his new mystery. His characters leap off the page, the plot is thrilling, and we see San Francisco and the era in amazing and fascinating realism. Ambrose Bierce appears here in great form, and each chapter opens with a quote from the Devil's Dictionary. I recommend this book highly! I just read an article today that says that his publisher can't print the books fast enough because they are flying off the shelf! Also check out his other recent book "Separations" a novel which you will never forget!
