Sarah and Max are getting married. But first they have to get Max out of jail.
Sarah Kelling has decided to spend a quiet, peaceful summer at the traditional Kelling summer place. If the bank wins its lawsuit, it will be the last chance she has to enjoy the property which holds so many memories for her. She's looking forward to time alone with Max to help make up her mind if she's ready to bury her late husband and move on.
But Sarah has relatives. Lots of them, mostly eccentric and many obnoxious. They all want a look at that Jew that Sarah is crazy enough to be thinking about marrying. And they want a chance to put a halt to it. No Jew is marrying into the Kelling-Larrington-Beaxitt clan if they can help it. A rich Jew would be different since money covers a multitude of sins even with snooty Boston Brahmins. But a Jew whose brother-in-law runs the local gas station? Not likely.
First sweet, but ditzy Aunt Appie shows up early. Then there's a cocktail party at the home of Miffy and Alice B, two harpies who love to stir up trouble. They start by reminding Max of an old girlfriend whom Sarah knows nothing about. Things go downhill from there.
The yacht club crowd still considers Sarah one of them, although it's been years since she's belonged. Dinners, drinking, and feuds are standard fare and they figure she won't want to miss a minute of it. The bad news is that there've been lots of burglaries from the empty houses of the summer folks. The burglar is taking expensive art works and leaving other items (such as silver) that would seem more salable. This burglar is an expert on art and its value.
Sarah has left little in her summer home to be stolen. Instead, someone has left her a present, a lovely Bilbao mirror that wasn't there before. Is someone setting her up to take the blame for the burglaries?
Aunt Appie's idiot son Lionel and his four sons have invited themselves to camp on Sarah's property for the summer. Lionel's wife has gone off to be a lesbian and he's looking for someone to dump the kids with. Sarah is determined it won't be her. And that's before the boys set fire to her boathouse.
Then there's not just a burglary, but a murder. Miffy's companion Alice B has been attacked by an ax and murdered. Shades of Lizzie Borden! Did Alice B interrupt a burglary in progress or did someone want her dead for another reason? How much money did the old girl have and who inherits it? In old-money families, that's always a consideration.
Meanwhile, Sarah's cousin Bradley Rovedock shows back up. He's the same age as her late husband Alexander with the same good looks and gentle manner. She remembers him fondly from childhood, but now he's determined to get her away from the evil influence of Max Bittersohn and back into the family fold. He thinks a marriage between them would be perfect. Sarah doesn't, but she has a hard time standing up to the people who've bullied her for so many years.
Bradley is the same age as her husband and she's comfortable with that. Sarah went from being a child in her parents' house to being a child in her husband's house. She's never been treated as an adult and it's tempting to crawl back to the known and let someone else make the decisions for her. Bradley is a nice guy and he's part of the world she grew up in. Max is an exotic stranger, exciting, but scary, too.
Sarah's met Max's sister and brother-in-law and likes their informal warmth, but she's too sensitive not to be aware that they're not thrilled by the prospect of Max marrying out of his clan. In proper Boston society, men from different social/religious groups know each other from business deals, but after-hours intermingling is nonexistent. Max understands the problems of a Boston Brahmin marrying a Jew and he wants to make sure Sarah understands them, too.
Sarah's family gathers to discuss the murder and the burglaries. As they start to connect the dots, they're convinced that the burglar must be someone who's an art expert because of the items selected to steal. From there, it's a quick jump to the outsider (Max) who showed up just as the burglaries started and poor Alice B was murdered. As Sarah looks on in horror, her relatives make a citizen's arrest. Max is tried and found guilty. Now there's no question of Sarah marrying him because he'll be in prison.
The sheriff (like most of the year-rounders) resents the snooty summer folks, but he's also intimidated by them. After all, they ARE rich, well-educated, and sophisticated. Can he afford for them to be mad at him? When one of the stolen items and the bloody ax are found hidden in the carriage house where Max is spending the summer, it looks like the case is closed. And satisfactorily for the Kelling-Larrington-Beaxitt clan, who would much rather accuse an outsider than a friend or relative.
Fortunately, Max's uncle is a lawyer and he's able to slow down the train until Max's friend Sargeant Jofferty can investigate. Also fortunately, Max (who specializes in thiefs of valuable art works) knows something about one of Sarah's relatives. Maybe the burglar/murderer wasn't an outsider after all.
The only objection I have to MacLeod's books is her habit of letting her amateur detective mull over the possible guilty parties and the pros and cons of each one. It takes time away from the action. Still, her mysteries are funny and smart and few writers have her talent for creating loony characters.
