Read on Serial Reader. Just about what I expect from an Agatha Christie: cozy, fairly danger-free mystery with some interesting characters and a bonus classic steamship trip. I don't know if the mystery was all that great but fun enough to follow along and not think about too deeply. The destination being Africa unfortunately means when the narrative has some needless racism (when it isn't just plainly ignoring Africans) and tops it off with some tired period gender roles towards the end.
