Jacobi continued to write macabre stories in the 1970s and 1980s. Many are collected in his final volume, "The Smoke of the Snake" (1994). His last published story, "A Quire of Foolscap" ("Whispers", Oct 1987) contains an in-joke: an unfaithful wife and her lover check into a motel "out on Carcosa", an obvious reference to both Ambrose Bierce's "An Inhabitant of Carcosa" and Robert W. Chambers' "The King in Yellow", as well as affectionate praise for Karl Edward Wagner's newly established publishing firm (see Carcosa).
