As the wife of retired ship's doctor Dr Henry Parker, Evelyn is living out her twilight years aboard the Golden Sunset. Every night she regales her fellow passengers with stories of a glamorous life travelling the world in luxury. The crew treat her with deference. And forbearance. But when Henry goes missing, Evelyn sets off to search every part of the grand ocean liner to find him, casino, nightclub and off-limits areas included. Misadventures are had, new friends are made, scandalous behaviour noted. If only she could remember the events of the night before as clearly as she can recall the first time she met Henry on a passage from England to Australia in 1953 and fell in love, abandoning her dreams to become a midwife to be a wife instead - and the long-ago painful events that left Evelyn all at sea. Why is it so hard to forget some things and so hard to remember others? And where is Henry?
