The Duke of Denver, accused of murder, stands trial for his life in the House of Lords.

Naturally, his brother Lord Peter Wimsey is investigating the crime - this is a family affair. The murder took place at the duke's shooting lodge and Lord Peter's sister was engaged to marry the dead man.

But why does the duke refuse to co-operate with the investigations? Can he really be guilty, or is he covering up for someone?

 
I used to enjoy watching the Lord Peter Wimsey mysteries on TV when I was a kid, and this one, I think, was one of the best. I'm really looking forward to reading this book, and the two other Sayers books I bought along with it to see if Wimsey is as funny as I remember him.
