An extensive history of the Detection Club, founded in 1930 in England. The author concentrates on three of the founding members (Dorothy L. Sayers, Anthony Berkeley and Agatha Christie) but also imparts interesting tidbits about many other mystery writers, especially those who flourished in the 1930's. If you are a fan of the above three novelists, this is a must-read. Edwards also recounts details of many classic Golden Age mysteries (and for the most part avoids spoilers), including how many plots were based on real life murders. The book contains many photos of Detection Club members and I found some books that I have put on my To Be Read list thanks to this book.
