Hercule Poirot is called in to investigate a case for an insurance company regarding firstly a dead woman's body found on a moor and then a important diamond sent to the company to be insured turns out to be a fake. Poirot discovers that the diamond was bought for Arlena Marshall by Sir Horace Platt and Arlena is on her honeymoon with her husband and step-daughter on a tropical island hotel. He joins them on the island and finds that everybody else starts to hate Arlena for different reasons - refusing to do a stage show, stopping a book, and for having an open affair with Patrick Redfern, another guest, in full view of his shy wife. So it's only a matter of time before Arlena turns up dead, strangled and Poirot must find out who it is...

In 1879 South Africa, the administrators of the British Cape Colony have designs to eliminate the Zulus as a hindrance to their colonial economy. To that end, the British present King Cetshwayo with an impossible ultimatum to provoke a war they are sure they can win easily with their rifles and artillery against native spears. However, that war proves more difficult than the arrogant British commander, Lord Chelmsford, expects as his overburdened army fruitlessly searches for the elusive enemy. However, in the shadow of a hill called Isandlwana, the overconfident British army learns to its sorrow just how badly they have underestimated the tactical skill and might of the Zulu nation.
