After the outbreak of WWII, Tommy and Tuppence are unofficially hired to sniff out Nazi spies at an English seaside resort…

Buckle your swashes (🤷🏼‍♀️), it’s Tommy and Tuppence adventure mystery time! Look, over 80 years later, it’s a little hard to take this one seriously - at times it feels a bit like Christie writing an episode of Dad’s Army (full disclosure: I’ve never actually watched Dad’s Army) - but nonetheless it was a fun puzzle. And clever, of course.

I figured out the identity of one of the spies, but I’m fairly sure I’ve previously read this one, so I’m not sure how much of that came from vague buried memories vs actually deducing it correctly. Either way, it was still a fun read - Tommy and Tuppence might be middle-aged now but they’re just as gung-ho as when they were Bright Young Things™ in their previous two books.

A swashbuckling WWII spy mystery romp, faintly ridiculous but nonetheless a good puzzle.
