Need I insist that the only enemy of the mature marriage is monogamy? That anything less than sexual multiplicity . . . is naive? That our sexual selves are merely idylers in a vast wood? Thus the central theme of John Hawkes's widely acclaimed novel The Blood Oranges is boldly asserted by its narrator, Cyril, the archetypal multisexualist. Likening himself to a white bull on Love's tapestry, he pursues his romantic vision in a primitive Mediterranean landscape. There two couples--Cyril and Fiona, Hugh and Catherine--mingle their loves in an lllyria that brings to mind the equally timeless countryside of Shakespeare's Twelfth Night.
