Peace, fresh air and good company was on the agenda for Inspector Tibbett's sailing holiday until Tibbett becomes fixated by a mysterious death from the past.
Inspector Henry Tibbett and his wife, Emmy, are enjoying a holiday on a friend's yacht, lazily sailing from one little English sea-town to the next.
It should all be delicious indolence... except that Henry can't stop thinking about death. Well, one death in particular. The death of a local sailor.
And he really can't stop thinking about it when it starts looking as though the drowned sailor is somehow connected to the robbery at a nearby manor house.
