only occasionally above the mindless rhythm, from across the narrow strait, over on the great African continent itself, a sound would arise to make the fog colder, the night darker, the Atlantic more menacing: if it were human it could have been called laughter, but it was not human. It was a product of alien secretions, boiling over into blood already choked and heady; causing ganglia to twitch, the field of night-vision to be grayed into shapes that threatened, putting an itch into every fiber, an unbalance, a general sensation of error that could only be nulled by those hideous paroxysms, those fat, spindleshaped bursts of air up the pharynx, counter-irritating the top of the mouth cavity, filling the nostrils, easing the prickliness under the jaw and down the center-line of the skull: it was the cry of the brown hyena called the strand wolf, who prowled the beach singly or with companions in search of shellfish, dead gulls, anything flesh and unmoving.
