An entertaining mystery about people who are too clever for their own good!
It's the beginning of WWII and people are moving away or into London as their risk tolerance and role in the war dictates. Archie is one of the young men who flock to London, in his case to prep for a career in the Foreign Office. There's nothing unusual about him, and so his friends and family are flabbergasted when he's found murdered. Or, perhaps not quite so, since he'd been victim of a couple of very nasty "accidents". When the police are called in, they try to connect the hit-and-run, the shove in the subway, the poisoned chocolates and his murder with the mysterious activities he'd been hinting at in the last couple of weeks before his death. It turns out that Archie fancied himself as a detective, but had grievously underestimated the cunning and ruthlessness of his opponent. Inspector Pardoe is convinced that the little sketches and clay models that Archie left behind refer to his secret adversary... but how to decode them?
This was a fun read, full of jaunty young men-about-town, faithful servants and gossipy old ladies. Exactly what one wants in a Golden Age mystery.
