It was supposed to be the perfect holiday - a group of families enjoying a week together in the sun. But Kate's husband is having an affair. She suspects the other woman is one of her two best friends. But which one? As she closes in on the truth in the stifling Mediterranean heat, she realises too late that the stakes are far higher than she ever imagined . . . Because someone in the villa may be prepared to kill to keep their secret hidden.
Seven days. Three families. One killer.
