The Man in the Brown Suit

Anne Beddingfeld, a spirited young woman who longs for adventure after her father's death, witnesses a strange accident at a London Underground station. Following a small clue, she sails to South Africa and is drawn into a tangle of diamonds, secret societies and a mysterious man she cannot quite place. The novel mixes mystery, romance and travel with a humorous, brisk narrator, and it shows Christie's lighter, more adventurous side outside her better-known detective series.
