"Mr. and Mrs. North have invited their closest friends--an ex-aviator, a mysterious doctor, and NYPD's own Lt. William Weigand--to join them on [a] glittering retreat, but the joviality ends when Weigand finds Helen Wilson lying across the path, a knife buried in her neck. A member of the group surely killed her, and unless the Norths act quickly, the murderer will strike again"--Back cover.

Frances and Richard Lockridge were some of the most popular names in mystery during the forties and fifties. Having written numerous novels and stories, the husband-and-wife team was most famous for their Mr. and Mrs. North Mysteries. What started in 1936 as a series of stories written for the New Yorker turned into twenty-six novels, including adaptions for Broadway, film, television, and radio. The Lockridges continued writing together until Frances's death in 1963, after which Richard discontinued the Mr. and Mrs. North series and wrote other works until his own death in 1982.
