Once he managed to force himself to visit Bodkin, found him resting quietly in his bunk, cooled by a homemade fan and the fading air-conditioner. Like himself, Bodkin seemed to be isolated on a small spur of reality in the centre of the time sea.

"Robert," he murmured through his swollen lips, "get away from here. Take her, the girl-" here he searched for the name "-Beatrice, and find another lagoon."

Kerans nodded, hunching himself inside the narrow cone of cool air projected by the air-conditioner. "I know, Alan, Strangman's insane and dangerous, but for some reason I can't leave yet. I don't know why, but there's something here-those naked streets." He gave up cloudily. "What is it? There's a strange incubus on my mind, I must lift it first."

Bodkin managed to sit up weakly. "Kerans, listen. Take her and go. Tonight. Time doesn't exist here now."

In the laboratory below a pallid brown scum was draped over the great semi-circle of progress charts, Bodkin's dismembered neuronic zodiac, and veiled the stranded benches and fume cupboards. Kerans made a half-hearted attempt to replace the charts that had fallen to the floor, then gave up and spent the next hour washing his silk dinner jacket in a pool of water left behind in one of the sinks.

Perhaps in imitation of himself, several of the crew now also sported tuxedos and black ties. A pantechnicon full of evening wear sealed inside water-tight envelopes had been found in one of the warehouses. Egged on by Strangman, half a dozen of the sailors dressed themselves up, bow ties around their bare necks, and pranced through the streets in tremendous glee, tails flaring and knees high-kicking, like a troupe of lunatic waiters at a dervish carnival.

After the initial abandon, the looting began to take on a more serious note. Whatever his private reasons, Strangman was solely interested in objets d'art, and after a careful reconnaissance identified one of the city's principal museums. But, to his annoyance, the building had been stripped, and his only salvage was a large mosaic which his men removed tile by tile from the entrance hail and laid out like a vast jig-saw on the observation deck of the depot ship.

This disappointment prompted Kerans to warn Bodkin that Strangman might try to vent his spleen on him, but when he climbed up to the testing station early the next evening he found that Bodkin had gone. The air-conditioner had exhausted its fuel, and Bodkin, deliberately it seemed, had opened the windows before he left, so that the entire station steamed like a cauldron.

Curiously, Bodkin's disappearance gave Kerans little concern. Immersed in himself, he merely assumed that the biologist had followed his own advice and moved out to one of the lagoons to the south.

Beatrice, however, was still there. Like Kerans, she had sunk into a private reverie. Kerans rarely saw her during the day, when she would be locked into her bedroom, but at midnight, when it became cool, she would always come down from her penthouse among the stars and join Strangman at his parties. She sat numbly beside him in her blue evening dress, her hair studded with three or four of the tiaras Strangman had looted from the old jewellery vaults, her breasts smothered under a mass of glittering chains and crescents, like a mad queen in a horror drama.

Strangman treated her with a strange deference, not unmarked by a polite hostility, almost as if she were a tribal totem, a deity whose power was responsible for their continued good fortune but nonetheless resented. Kerans tried to stay near her, within her orbit of protection, and the evening after Bodkin's disappearance leaned across the cushions to say: "Alan's gone. Old Bodkin. Did he see you before he left?"

But Beatrice stared out over the fires burning in the square, without looking at him said in a vague voice: "Listen to the drumming, Robert. How many suns are there, do you think?"

Wilder now than Kerans had ever seen him, Strangman danced about the camp fires, sometimes forcing Kerans to join him, inciting the bongo drummers to ever faster rhythms. Then, exhausted, he would slump back on his divan, his thin white face like blue chalk.

Leaning on one elbow, he stared sombrely at Kerans, squatting on a cushion behind him.

"Do you know why they fear me, Kerans? The Admiral, Big Caesar and the others. Let me tell you my secret." Then, in a whisper: "Because they think I'm dead."

In a spasm of laughter, he rocked back into the divan, shaking helplessly. "Oh, my God, Kerans! What's the matter with you two. Come out of that trance." He looked up as Big Caesar approached, doffing the dried alligator's head which he wore like a hood over his own. "Yes, what is it? A special song for Doctor Kerans? Capital! Did you hear that, Doctor? Let's go then, with _The Ballad of Mistah Bones!_"

Clearing his throat, with much prancing and gesticulation, the big negro began, his voice deep and guttural.

With a sudden shout, Strangman leapt from the divan, raced past Big Caesar into the centre of the square, pointing up at the perimeter wall of the lagoon high above them. Outlined against the setting sky was the small square figure of Dr. Bodkin, picking his way slowly across the wooden barrage that held back the creek waters outside. Unaware that he had been spotted by the party below, he carried a small wooden box in one hand, a faint light fizzing from a trailing wire.

Wide awake, Strangman bellowed: "Admiral, Big Caesar! Get him, he's got a bomb!"

In a wild scramble the party dissolved, with the exception of Beatrice and Kerans everyone raced off across the square. Shotguns slammed left and right, and Bodkin paused uncertainly, the fuse wire sparking about his legs. Then he turned and began to edge. back along the barrage.

Kerans jumped to his feet and ran after the others. As he reached the perimeter wall star-shells were bursting into the air, spitting magnesium fragments across the roadway. Strangman and the Admiral were leaping up a fire escape, Big Caesar's shotgun slamming out over their heads. Bodkin had left the bomb in the centre of the dam and was racing away over the rooftops.

Straddling the final ledge, Strangman leapt up on to the barrage, in a dozen strides reached the bomb and kicked it out into the centre of the creek. As the splash died away a cheer of approval went up from those below. Catching his breath, Strangman buttoned his jacket, then slipped a short-barrelled.38 from his shoulder holster. A thin smile glittered on his face. Whipping on the cries of his followers, he set out after Bodkin as he scaled his way painfully up the pontoon of the testing station.

Kerans listened numbly to the final shots, remembering Bodkin's warning and the necessity, for which he bore him no grudge as he had chosen to ignore it, of being swept away himself with Strangman and his crew. He walked slowly back to the square, where Beatrice still sat on the heap of cushions, the alligator head on the ground in front of her. As he reached her he heard the footsteps behind him slowing menacingly, a strange silence fall over the pack.

He swung around to see Strangman saunter forward, a smirk twisting his lips. Big Caesar and the Admiral were at his shoulder, their shotguns exchanged for machetes. The rest of the crew fanned out in a loose semi-circle, watching expectantly, obviously pleased to see Kerans, the aloof medicine-man of a rival juju, get his just deserts.

"That was rather stupid of Bodkin, don't you think, Doctor? Dangerous too, as a matter of fact. We could damn nearly have all been drowned." Strangman paused a few feet from Kerans, eyeing him moodily. "You knew Bodkin pretty well, I'm surprised you didn't anticipate that. I don't know whether I should take any more chances with mad biologists."

He was about to gesture to Big Caesar when Beatrice jumped to her feet and rushed over to Strangman.

"Strangman! For heaven's sake, one's enough. Stop it, we won't hurt you! Look, you can have all these!"

With a wrench she unclasped the mass of necklaces, tore the tiaras from her hair and flung them at Strangman. Snarling with anger, Strangman kicked them into the gutter, and Big Caesar stepped past her, the machete swinging upward.

"Strangman!" Beatrice threw herself at Strangman, stumbled and almost dragged him to the ground by his lapels. "You white devil, can't you leave us alone?"

Strangman twisted her away, breath seething through his clenched teeth. He gazed wildly at the dishevelled woman down on her knees among the jewels, and was about to wave Big Caesar on when a sudden intention tremor flickered across his right cheek. He slapped at it with his open hand, trying to brush it away like a fly, then flexed his facial muscles in an ugly grimace, unable to master the spasm. For a moment his face was twisted in a grotesque gape, like a man struggling in lock-jaw. Aware of his master's indecision, Big Caesar hesitated, and Kerans moved backwards into the shadows under the depot ship.

"All right! God, what a…!" Strangman muttered something thickly to himself and straightened his jacket, the point grudgingly conceded. The tic had faded. He nodded slowly at Beatrice, as if warning her that any future intercessions would be ignored, then barked sharply at Big Caesar. The machetes were tossed aside, but before Beatrice could protest again the entire pack threw itself on Kerans with a series of whoops and yells, hands flailing and clapping.

Kerans tried to sidestep them, uncertain from the circle of grinning faces whether this was merely some elaborate form of horseplay intended to discharge the tension that Bodkin's murder had generated, and at the same time administer a salutary reproof. He skipped around Strangman's divan as the pack closed in, found his escape blocked by the Admiral, who was feinting from side to side in his white tennis shoes like a dancer. Suddenly he sprang forwards and kicked Kerans' feet from under him. Kerans sat down heavily on the divan, and a dozen, oily brown-skinned arms seized him around the neck and shoulders and somersaulted him backwards onto the cobbled ground. He struggled helplessly to free himself, had a glimpse through the panting bodies of Strangman and Beatrice watching from the distance. Taking her arm, Strangman drew her firmly towards the gangway.
