Murder on the High Sea (The Blind Sleuth Mysteries Book 5‪)‬

In 1960 Daisy Hayes was asked to replace a physiotherapist on an ocean liner, for just one round trip to New York, at very short notice. Before she knew it she was sailing on the RMS Histria, in the thick of the life on board. With the intrigues and love triangles going on around her, she marveled at the potential for murderous plots on such a voyage. “It’s a good thing,” she told the ship’s detective, “that a liner at sea is a very bad place for killing someone. Too confined to do it undetected, and you can’t get away afterwards.”
Then one day at dawn a corpse was found floating on the open ocean ahead of the Histria. The ship came to a lumbering halt, a launch was sent out to retrieve the dead body, and while some early birds watched from the rails, it was hoisted on board. And the corpse turned out to be that of a first-class passenger.
Impossible! Or isn’t it? Our favorite blind sleuth could hardly wait to find out.
