Poisoning whodunnit set among expatriates in a desert location. Seven people are relaxing round a tennis court. Harvey Paynton, dishonest and a womaniser, drinks a glass of orange juice and is poisoned. The six others drinking from the same jug are safe. It is months before anyone works out how it was done.
