Garden City, Doubleday/Crime Club, 1976. First edition. An apparently idyllic Fourth of July party turns deadly when a mermaid is murdered. Yes, a mermaid. Photojournalist Helen Bullock, a childhood friend of the deceased, will try to get to the bottom of the affair, even though she might be the next victim! Fine in near fine DJ, the latter showing just a touch of wear. $15.00.
