Brought home from the library by my husband.
Daisy is still writing her "homes of the rich and famous" articles although she's married Alec, giving her either more or less access to his Scotland Yard cases.
In this story Daisy is writing a Guy Fox Celebration article for an American magazine and is visiting Edge Manor where Sir Harold Tyndall is reputed to have a spectacular 5th of Nov. bonfire and fireworks display. She has an in there since she went to school with Gwen, one of Sir Harold's three daughters. Also in the household are Barbara, Gwen's sister, and Jack, her brother and Sir Harold's heir. Nearby are their sister Adelaide, widowed by the War, and her mother-in-law. Also Addie's two preteen sons, whom Alec describes as criminals in training, are home for midterm break.
There is a great deal of tension in the house because Jack wants to be an aeronautical engineer and has brought Miller, an engineer from a local aviation firm , to help convince his father. Since his father calls Miller a bounder there doesn't seem to be much hope there.
Things remain below boiling point until the festivities begin. The criminals in training have removed some of the rockets from the display and Jack chases after them. All the county families are there for the event so it is unfortunate that Jack catches Addie in the middle of the dining room where all the guests are filling their plates and lights into her about her sons' behaviour. Their mother points out their lack of manners but it is only a few minutes before manners are the least of the family's worries. Sir Harold is discovered dead at his study desk near a visiting Australian woman who is staying at the local inn with her husband and whom Jack invited up to the house for the bonfire.
Alec is called in and it all becomes very messy, since the estate covers parts of two counties and the Lord Lieutenant of one and the Chief Constable of the other were among the guests. I have a question: how are lord lieutenants and chief constables appointed? I'm assuming the positions are in the monarch's gift but do they tend to be inherited? Alec says the chief constable is only a courtesy policeman, so is the position there to make sure that there is some supervision of police work by someone of "good" family? The lord lieutenant is described as having only a ceremonial function so what does he do?
The characters are all believable, even Mr. Gooch, the Australian's husband. The antedeluvian butler is rather a nice touch, since if they had pensioned him off where would they have found another? There is perhaps a little too much slipping outside for a walk so characters can have a quiet chat but I sympathise with Alec who really does need a little privacy to question witnesses.
It does have a satisfying ending, even regarding those boys who are definitely in for a sharp shock when they arrive at boarding school.
