Aird is one of those authors who have been writing and publishing forever, but whom many avid mystery fans have never heard of. Her principal work has been the sixteen-volume “Calleshire Chronicles” series, which began in 1966. The most recent episode came out in 2019, when Aird was ninety, and a fifty-three year run (so far) is nothing to sneeze at.
The protagonists of the series are Detective Inspector C. D. Sloan (a “copper’s copper,” as they say, and head of the local CID) and Detective Constable Crosby (who is a constant trial to his superiors, but not a bad sort). The thing is, these two, plus Superintendent Leeyes and a few other regulars, haven’t aged a day in the past half-century. The background changes, keeping up with the real world, but the characters never do. Which means that, unlike detectives in other series, they never get promoted, but they’re also never going to be forced to retire or get too old to do the job. Which means, in turn, that you can pick up any of the books in any order -- which is useful, because I’ve only come across them randomly over the years.
The story this time is a little unusual, and it's heavy on the philosophy of English law. Kenneth Carline, a young and very junior civil engineer, has died of poisoning, which apparently was delivered in a bowl of chili, the spiciness of which masked the drug. The chili was prepared for him, purportedly on the spur of the moment, by Lucy Durmast, his boss’s 21-year-old daughter. All this happened a year ago, and not even on Sloan’s patch, but the DI who had the case originally (and apparently did everything properly) suffered a brain injury and can no longer function, so Sloan has to step in now that the case is about to go to trial.
But ever since her arrest, Lucy has insisted on standing mute -- and no one can figure out why. She had no motive that anyone can discover, or even imagine. But she’s very far from stupid, or nloody-minded, and everyone who knows her is convinced she has a good reason for not speaking a word to anyone. The whole thing really bothers Sloan, who doesn’t like circumstances that can’t be explained, so he attempts to investigate the whole case from the beginning. But things have change in a year, of course: Mr. Durmast is off in Africa, designing a new capital city for an “emergent nation,” and young Carline’s old school chum, the son of the king of that nation (and who opposes building that new capital) has disappeared. So what actually happened? And why is Lucy mute, even though it’s gotten her sentenced for contempt of court?
Sloan is doing a lot a head-scratching, and so will the reader. The clues are there (Aird always plays fair), but they’re subtle. Fair warning, too: The author’s vocabulary tends to be more advanced (or better educated) than that of probably most of her potential 21st-century audience, so you may want to keep a dictionary handy. There’s also a good deal of humor, but it’s of the sly and sneaky sort, which is very much to my own taste. If you don’t know Aird’s books, I recommend you pick one up -- any of them, because they’re all entertaining.
