I found Whose Body? for free for my kindle. I read Sayers's Murder Must Advertise a couple years ago and wasn't that thrilled. Murder Must Advertise is on the 1001 Books You Must Read list so when I didn't like it I didn't think I'd pick up any other books by Sayers.
But as I mentioned I found this for free, so I figured I'd give it a chance.
I really enjoyed it! Lord Peter Wimsey is the second son in a British aristocratic family. This book was written in 1923. Lord Peter is a veteran of WWI and solves mysteries as a hobby. My favorite part was Bunter, Lord Peter's butler. He made me laugh out loud several times.
In this book, a wealth financier is missing while a body resembling the man turns up naked in soemone's bath tub. Lord Peter hears about the case from his mother, who at times lends him a hand. He sets out to solve the mystery at the annoyance of Police Inspector Sugg. I found the mystery to be somewhat predictable, but the characters more than made up for that.
If you like Agatha Christie, I think you'd like the Lord Peter books. I already ordered the second book in the series, Clouds of Witness, for my Kindle. At 99 cents, why not?
