The Mermaid and Mrs. Hancock by Imogen Hermes Gowar
In London, 1785, sensible Jonah Hancock’s fortunes take a dramatic turn when he comes into possession of the shriveled body of a dead mermaid. The creature quickly attracts the attention of a local madame who uses it as a burlesque sideshow attraction—described by Kirkus Reviews as a scene “that would make HBO executives blush”—and entwines Jonah with the shrewd, beautiful prostitute Angelica.
