I have seen some reviewers say that they didn't like how some of the cases in this book were dated, and it is true; some of the cases do date from as far back as 1944 (although the cases travel forward in time to the 1990s).Instead of being a detriment, this only makes the book better. Because in the 1940s and even in the 1950s, we did not have the technology that we have today. Therefore, the author relied upon instinct and good old fashioned detective work. That makes the mysteries of these very odd diseases outlined in this book to be even more fascinating.This is a good book. Each chapter dwells on a different, odd and unusual illness, and it is up to the author to get to the bottom of what, where, and how. This book would make a good TV series. I recommend it. Although not cutting-edge technology, it has its charms by relating human intelligence and human curiousity, and it will certainly keep your interest.
