naturalist, he made his own descriptive notes of the changing flora and fauna, employing a taxonomic system of his own devising. In one of his few unguarded moments he had shown the notebooks to Kerans, then abruptly withdrawn into himself when Kerans tactfully pointed out that the classifications were confused.
For the first two years Hardman had been the perfect buffer between Riggs and Kerans. The rest of the crew took their cue from the Lieutenant, and this had the advantage, from Kerans' point of view, that the group never developed that sense of happy cohesion a more extravert second-in-command might have instilled, and which would have soon made life unbearable. The loose fragmentary relationships aboard the base, where a replacement was accepted as a fully paid up member of the crew within five minutes and no-one cared whether he had been there two days or two years, was largely a reflection of Hardman's temperament. When he organised a basketball match or a regatta out on the lagoon there was no self-conscious boisterousness, but a laconic indifference to whether anyone took part or not.
Recently, however, the more sombre elements in Hardman's personality had begun to predominate. Two months earlier he complained to Kerans of intermittent insomnia—often, from Beatrice Dahl's apartment, Kerans would watch him long after midnight standing in the moonlight beside the helicopter on the roof of the base, looking out across the silent lagoon—and then took advantage of an attack of malaria to excuse himself from flying duty. Confined to his cabin for up to a week on end, he steadily retreated into his private world, going through his old note-books and running his fingers, like a blind man reading Braille, across the glass display cases with their few mounted butterflies and giant moths.
The malaise had not been difficult to diagnose. Kerans recognised the same symptoms he had seen in himself, an accelerated entry Into his own 'zone of transit', and left the Lieutenant alone, asking Bodkin to call in periodically.
Curiously, however, Bodkin had taken a more serious view of Hardman's illness.
Pushing back the door, Kerans stepped quietly into the darkened room, pausing in the corner by the ventilator shaft as Bodkin raised a monitory hand towards him. The blinds over the windows were drawn, and to Kerans' surprise the air-conditioning unit had been switched off. The air pumped in through the ventilator was never more than twenty degrees below the ambient temperature of the lagoon, and the air-conditioner normally kept the room at an even 70 degrees. But Bodkin had not only switched this off but plugged a small electric fire into the shaver socket over the hand basin mirror. Kerans remembered him building the fire in the laboratory at the testing station, fitting a dented paraboloid mirror around the single filament. Little more than a couple of watts in strength, the fire seemed to emit an immense heat, blazing out into the small room like a furnace mouth, and within a few seconds Kerans felt the sweat gathering around his neck. Bodkin, sitting on the metal bedside chair with his back to the fire, was still wearing his white cotton jacket, stained by two wide patches of sweat that touched between his shoulder blades, and in the dim red light Kerans could see the moisture beading off his head like drops of white-hot lead.
Hardman lay slumped back on one elbow, his broad chest and shoulders filling the backrest, big hands holding the leads of a pair of headphones clasped to his ears. His narrow, large-jawed face was pointed towards Kerans, but his eyes were fixed on the electric fire. Projected by the parabolic bowl, a circular disc of intense red light three feet in diameter covered the wall of the cabin, Hardman's head at its centre, like an enormous glowing halo.
A faint scratching noise came from a portable record player on the floor at Bodkin's feet, a single three-inch disc spinning on its turntable. Generated
