Georgette Heyer is a wonderful author whose mysteries never fail to make me smile.
Frank Amberley is on his way into the country but his young cousin's promised shortcut has only gotten him hopelessly lost. And now he's stumbled upon a murder. The young woman who is also at the site is nervous but he's sure she's not the one who did this foul deed. So he lets her go and then phones the police.
Mr. Amberley is apparently not a favorite of the Inspector in this area, having shown the man up before, so when he starts making suggestions, the Inspector tends to try and do the opposite.
The young woman shows up again, renting a local cottage with her brother. The brother Mark is a horrible drunk and a constant worry to his sister, Shirley. But they seem to be in town for a specific reason.
The other major players are are a young man, Fountain, and his step-sister. The step-sister is a particular friend of Frank's cousin and she is about to be married. Their house is rather a gloomy one, even though the young man just came into his uncle's fortune. The murdered man turns out turns to have been their butler. Now the role is being filled by Fountain's valet, Collins, a thoroughly unlikable man, at least from the author's description.
Two more murders round out the book before one last attempt at a murder before the criminal can be rounded up. Rather good read.
