The story's title is taken from "The Tower Beyond Tragedy," a 1950 poetic drama by California-based poet and playwright Robinson Jeffers (1887-1962). The character of Amory Gilliam makes several references to Jeffers' writings and to the granite stone Tor House and Hawk Tower that Jeffers constructed in Carmel, California.
This episode bears a number of interesting resemblances to the Alfred Hitchcock movie "Vertigo," including some of the locations like Fort Point, and the story of a man trying to control and remodel a woman to fit his ideal image.
The location of the castle in Tower Beyond Tragedy was not in Monterey , California that Stone and Keller raced to in hops of catching the killer . In fact , is was at the historical Sam's Castle in nearby Pacifica where the final segment was filmed .
French title: La tragédie de la tour.
The artwork featured in this episode is called "Blue Nude I" (French: "Nu Bleu I"), by French painter Henri Matisse. It was part of a series of decoupages or related color lithographs called "The Blue Nudes", which were completed in 1952. Originally a painter, Matisse fell ill with cancer in 1941, which prevented him from painting, so he took up collages. "The Blue Nudes" are among Matisse's final body of works, as he died in November 1954 at the age of 84.
