Josephine Tey was fascinated by people who are not what they seem; these three tales feature scheming schoolgirls, twins and impostors, and young women driven by ambition. The subtitle could be “watch out for young people,” and you could interpret these as responses to a postwar world in which youth were overturning long-held traditions, with all the moral and ethical conundrums that go along with that upheaval. ‘Miss Pym Disposes’ successfully recreates the world of a girls’ school; mystery doesn’t come into it until 2/3 of the way through, but the creation of their world is still compelling. In ‘Brat Farrah,’ the heir to Latchetts comes back from the dead—we know he’s an impostor from the beginning, but who else knows and what will they do about it? This one’s a slow burn and it’s the characters and relationships that keep you reading. I struggled a bit more with ‘The Franchise Affair,’ kind of a baggy story with less-than-compelling characters. Out of the blue, a teenaged girl accuses two elderly ladies of unspeakable crimes against her and the community takes up arms when the prosecutor finds insufficient evidence for a trial. An interesting idea that looks at the responsibility of police and the newspaper in meting out justice, but somehow it doesn’t quite gel. Still, Tey at her best.
