This delightful mystery is the second featuring Lord Peter Wimsey. When his brother, the Duke of Denver, is accused of murder then it is Lord Peter's job to clear his name. The Duke is found standing over the body of his sister's fianc , who he has recently argued with about claims that the victim, Captain Denis Cathcart, was a card sharp. However, when questioned, he refuses to give a reasonable account of why he was wandering around outside, in the middle of the night. Why is he being so secretive and what is their sister, Mary, hiding? This is a wonderful, Golden Age mystery, with Lord Peter Wimsey and Charles Parker truly collaborating. There are some great, atmospheric scenes, most notably when Wimsey and Bunter are lost on the moors. The scenes in the House of Lords, where the Duke of Denver is tried, are also very interesting. Much of the fun in these books is in Wimsey himself and his light-hearted banter and eccentric behaviour. He is one of the greatest fictional amateur detectives and this is one of his best cases.

The fianc of Lord Peter's sister, Mary, is found dead outside the conservatory of the family's shooting lodge in Yorkshire. Peter's and Mary's older brother, the Duke of Denver, is charged with wilful murder and put on trial in the House of Lords. How can detective Lord Peter proceed when it's a murder in his own family potentially by his own brother?
