This had the potential to be a fun thriller (much like The Secret of Chimneys and The Seven Dials Mystery), which I actually like better than Christie's better-known puzzle mysteries. But much of it is set in South Africa and Rhodesia, against the backdrop of empire, and as I had just finished reading Trevor Noah's "Born a Crime," this proved to be a problem for me. The light breeziness of English tourists is harder to swallow when you know what's going on with the native population. De Beers plays a small role--that's right, the blood diamond company!

Aside from this, I didn't love the first person narration, and the plot was a bit too convoluted for my taste.

The last third of the novel flew by, though. Still, too much wrong. Would not recommend.
