An interesting juxtaposition of similar serial murder cases in the same city, 500 years apart. The book regularly jumps back and forth between the eras, sort of paralleling the two developing stories. Imaginative, though, frankly, a little bit contrived. The creativity works better in the first half of the book, while the reader is still curious. It appears that the writer kind of wore out her creative muse, though, and struggled to find endings to the cases that made any sense. The solution to the 500 year old case was kind of a cop out. But, the book is relatively short, and interesting read, and as rated, it's okay.
