An elderly amateur sleuth opens her newspaper to learn that Jason Rafiel, the irascible millionaire she befriended during a Caribbean holiday, has died. Soon afterwards his solicitors deliver a posthumous letter: Rafiel offers her a substantial bequest if she agrees to investigate a crime. The catch is that he names no victim, no place, and no date. He trusts her instinct for justice and her sense of evil to lead her where she needs to go. With almost nothing to work from, she accepts and finds herself booked, at Rafiel's arrangement, onto a coach tour of famous houses and gardens across the English countryside. Among her fellow travellers and the people she meets along the route, an old tragedy begins to surface, one rooted in a young woman's death years before. Each conversation and each stop adds another fragment, and the past pulls steadily into focus. Working without official standing, armed only with patience, memory, and a willingness to listen, she pieces together motive and meaning from gossip, half-truths, and the things people prefer to leave unsaid. The story unfolds as a quiet study of guilt, love that curdles, and the long reach of wrongdoing, with its protagonist cast as an agent of reckoning. It moves at the measured pace of village talk and garden walks while a sense of menace gathers beneath the genteel surface, building toward a confrontation with the truth Rafiel wanted exposed.
