Retired bank manager Henry Pulling is happy alone with his dahlias. Until, at his mother's funeral, he meets his only living relative, the decidedly bohemian Aunt Augusta. After she's rattled the family skeletons, she suggests the pair flee to Europe. Henry is reluctant, but Aunt Augusta is nothing if not persuasive. Through Paris and Istanbul and on to South America, Henry soon finds himself in a luxurious whirl of glamorous flight attendants, chic hotel suites and a particularly fine couchette on the Orient Express. But alongside the romance and first-class thrills, there's still a lot Henry doesn't know about his aunt. Particularly how she's paying for the high life, and why she has so many grateful men dotted around the globe.
