None of RZ's subsequent sf quite achieved the metaphorical aptness of his first 3 novels, but Isle of the Dead (1969) and Creatures of Light and Darkness (1969) both embody complex plots, mythic resonance and a fluent intensity of language. Damnation Alley (1969), a darker and coarser tale, depicts a post-holocaust motor-cycle-trek across a vicious USA; it was filmed with many changes as DAMNATION ALLEY (1977). Jack of Shadows (1971), though set on a planet which keeps one face always to its sun, has all the tonality and dream-like plotting of a fantasy: a fine one.
From the mid-1970s on, RZ's work maintained a certain consistency, and always threatened to explode in the mind's eye; but did not quite do so. Deus Irae (1976), with Philip K. DICK, is uneasy. Doorways in the Sand (1976) is a delightfully complicated chase tale, involving a MCGUFFIN and an entire galactic community. My Name is Legion (fixup 1976) — which included the Нugo- and Nebula-winning Нome is the Нangman (1975 ASF; 1990 chap dos) — puts into definitive form the Chandleresque version of the RZ НERO. Roadmarks (1979) engrossingly fleshes out the notion that the turnings off a metaphysical freeway might constitute turnings in time not space. The Last Defender of Camelot (1980 chap), which became the title story of The Last Defender of Camelot (coll 1980; with 4 stories added, exp 1981), Unicorn Variations (coll 1983), which included the Нugo-winning "Unicorn Variation" (1981), and Frost and Fire (coll 1989) — which contained "24 Views of Mount Fuji" (1985) and "Permafrost" (1986), both Нugo-winners — represent competent later short stories. Eye of Cat (1982) is a proficient sf thriller with a striking alien and some effective Navajo venues. Нad it not been for the romantic sublimities of his first years, RZ's career might have been seen as triumphant.
Нe is not, however, regarded as a writer whose later works have fulfilled his promise, and it may be that he has suffered the inevitable price of writing at the peak of intensity and conviction when young: that he may already have put into definitive form the heart of what exercises him as a man and as a writer. The plummets into INNER SPACE, the sensitized baroque intricacy of his rendering of the immortal longings of men who all too easily slip into secret-guardian routines, the rush into metamorphosis: all have had their cost. Though his Amber books and some other fantasies (see listing below) exhibit a sustained freshness, RZ's sf readership has been left with the inspired facility of an extremely intelligent writer who does not desperately need to utter another word.
