Lady Rose Summer is engaged to Captain Harry Cathcart - a private investigator. But she is getting rather tired of him not attending social functions with her because he is busy on cases. She makes friends with Dolly Tremaine, a debutante only to find her murdered body when she goes to meet her in Hyde Park one morning. This puts Lady Rose and her companion Daisy Levine in personal danger and they are forced to take drastic action to avoid coming to a sticky end.
Rose as ever gets herself into some sticky situations simply because she is bored and curious. At times it seems as though she and Harry are finally seeing eye to eye and then they are at daggers drawn again. Will their engagement - which was only entered into to stop Rose's parents shipping her off to India - survive their latest arguments?
I enjoyed this third book in the series as the regular characters are developing - Harry and Rose, Daisy and Harry's manservant Becket. I like the style of writing which has the down to earth quality evident in this author's other two series - Agatha Raisin and Hamish Macbeth. I also like the historical background to the story which shows clearly how differently women were treated only one hundred years ago.
