Night of the Ripper (1984), was another return to one of Bloch's favourite themes, the Jack the Ripper murders of 1888. In 1986, Scream Press published the hardcover omnibus Unholy Trinity, collecting three by now scarce Bloch novels, The Scarf, The Dead Beat, and The Couch. A second retrospective selection of Bloch's nonfiction was published by NESFA Press as Out of My Head. In 1987, Bloch celebrated his 70th birthday. Underwood-Miller issued the three-volume hardcover set The Selected Stories of Robert Bloch (individual volumes titled Final Reckonings, Bitter Ends and Last Rites). When Citadel Press reissued this in paperback they incorrectly named it The Collected Stories of Robert Bloch. The same year a collection, Midnight Pleasures appeared from Doubleday, and Lost in Time and Space with Lefty Feep (Creatures at Large Press) collected a number of the stories on the Lefty Feep series. The latter was the first of a projected series of three volumes, but the further volumes were never published. In 1988, Tor Books reissued Bloch's scarce second novel, The Kidnapper. In 1989, several works were published: the collection Fear and Trembling, the thriller novel Lori (later adapted as a standalone graphic novel) and another omnibus of long out-of-print early novels, Screams (containing The Will to Kill, Firebug, and The Star Stalker). Randall D. Larson issued The Robert Bloch Companion: Collected Interviews 1969-1986 (Starmont House), together with Robert Bloch (Starmont Reader's Guide No 37), an exhaustive study of Bloch's work, and The Complete Robert Bloch: An Illustrated, Comprehensive Bibliography (Fandom Unlimited Enterprises). Larson's three books were bound in hardcover and distributed by Borgo Press. The 1990s: Last works Bloch's novel, The Jekyll Legacy (1990), was a collaboration with Andre Norton and a sequel to Robert Louis Stevenson's Dr. Jekyll and Mr. Hyde. The same year he returned to the Norman Bates "mythos" with Psycho House (Tor), the third Psycho novel. As with the second novel in the sequence, it bears no relation to the film titled Psycho III. It would prove to be his last published novel. In February 1991, he was given the Honor of Master of Ceremonies at the first World Horror Convention held in Nashville, Tennessee. Weird Tales issued a special Robert Bloch issue in Spring, including his screenplay for the televised version of his tale "Beetles"". A standalone chapbook of the story "Yours Truly, Jack the Ripper" was issued in both hardcover and paperback
