Phoebe Atwood Taylor (1909-1976) wrote eight novels under the name Alice Tilton, all featuring Leonidas Xenophon Witherall.
In this, the first in the series, originally published in 1937, Witherall is a janitor of a building in which there is a bookshop where a murder is committed. He was once a teacher, but has lost his money as a result of the Depression.A former pupil is accused of the murder of his ex-boss, the head of museum from which a large sum in bonds has gone missing.
Witherall, along with Dot, the bookshop owner, Agatha Jordan, a Bostonian widow,and Gerty McInnis and her gangster boyfriend, set out to prove the police wrong.
This is more of a caper or a romp, albeit with dark overtones, than a detective novel. We know fairly early on who is guilty, and the novel is, from then on, a catalogue of (mis)adventures on the way to the solution.
It is immensely readable and full of occasionally rather grim fun. The Boston setting is well-evoked.
This edition is great value and I will read more of the series.
3.5 stars.
