Actually, some of the Books of Blood, Barker's ground-breaking six-volume British paperback set of horror tales.
Of the six, Vols. 4 and 5 have appeared here in hard-cover (as The Inhuman Condition and In the Flesh, respectively, both 1986) and Vols. 1-3 as mass-market paperbacks. This edition encompasses those first three volumes (which are the three best), a collection of short horror fiction unmatched anywhere, anytime, for ferocity and intensity of vision. One story, "Rawhide Rex," was made into a film released in 1987; another, "In the Hills, the Cities," contains Barker's greatest conceit.
A must addition to horror collections.
