"Leave your basket here, but bring your pole-grab and net," said Ulat, standing beside the pond with three other pond workers. Eldene glanced at him, then carefully made her way to the edge of the pond, towing her net full of broken deaders behind her. The squerms in this pond were only small ones — less than the length of her arm and only the thickness of her thumb — but you never dared take your eye off them for long. Even ones this size could writhe up the side of a wader to tear holes in a worker's body.

Reaching the bank she climbed out of the water and emptied her net. As Ulat and the others began to move away, she took up her pole-grab then hurried to catch up, falling in beside Fethan. The man was an old hand who had been working the ponds for more than half his life, hence the huge bulge apparent on his chest — over which his ginger beard spread — where his scole lay feeding under his shirt.

"What's happening?" Eldene hissed.

Fethan glanced at her with bloodshot eyes, then twisted his face in a parody of a grin, exposing his lack of front teeth — apparently lost when he had taken a beating from one of the town proctors. "Tricone. Musta been a faulty membrane. Broke through into one of Dent's ponds and drowned — poisoned half the squerms."

Eldene felt fear clenching her gut: that meant half a pondful of deaders to remove. "What size?" she asked.

"Full-grown squerms," Fethan replied, then lowered his voice. "Now'd be a good time to go under. Guarantee one of us'll get scraped today."

Eldene considered that. Fethan had teased her remorselessly about 'the Underground' — occasionally saying something to pique her curiosity, then dismissing it all as rumour and myth. Eldene thought it likely that it was all myth. She had so far seen no sign of a resistance movement, but plenty of signs of something to resist. She glanced up at the satellites and stations of the Theocracy glinting in the now lavender sky, or across the face of the gas giant, all reflecting the light of the sun that would shortly break from behind the horizon. Then she gazed out across the ponds, to where Proctor Volus was rapidly approaching in his aerofan with its side-mounted rail-gun. What chance did any resistance movement stand with satellite lasers poised overhead, and the Theocracy's religious police below constantly watching the planet-bound population?

It was evident they had reached the pond in question when Ulat halted and stood gazing at the water, with arms akimbo. Dent stood at the foreman's side, wringing his hands, his balding head bowed. That a tricone had broken through the membrane separating the pond's water from the deep planetary soil was not due to any fault on his part. In fact it was more likely due to skimming on Ulat's part — trying to make a membrane last for three seasons, rather than the usual two, and pocketing the consequent saving. But, as Eldene well knew, blame always devolved on the workers, no matter how innocent.

"You checked it before it was filled?" Ulat asked, after hinging down his mask. Because he used such breather gear showed he was a citizen, rather than just a worker, but it did not raise him to the rank of a true brother. All that could impart that lofty status was the Gift, which only those of religious rank above vicar could bestow.

"I did, Ulat," replied Dent.

Ulat flipped his mask back up as he studied the pond again. In the shallow water rested a mollusc the size of a man's torso. This creature consisted of three white cones of shell closely joined, like panpipes, but with nodular fleshy heads resting deep within each shell mouth. All around it the water was discoloured, bluish, and the only squerms anywhere near it were either unmoving or breaking up into individual segments. The rest of the squerms were gathered around the edges of the pond, tangled in the mat of weeds in a hissing and flicking, vicious metallic spaghetti. As Ulat glanced round to where Volus was landing his aerofan, the mask did not conceal an alarmed but furtive expression. Eldene understood that, with the Proctor being here now, Ulat had no chance to cover up the disaster and put the loss down to the natural wastage entailed by deaders. Someone, she knew, was going to be punished.

"I think not," said Ulat, and abruptly struck Dent across the face. When the man went down, Ulat kicked him in the stomach. Then, as he coiled around this pain, Ulat stamped down on the scole attached to his chest — which soon had Dent gasping for breath as the creature ceased to oxygenate his blood.

"What has happened here, brother?" asked Volus, approaching, his voice echoey behind his tinted visor.

Eldene studied the new arrival, with his stinger resting across one shoulder and his pistol drawn from its recharging holster, and realized that the rumours were true: Volus had received the Gift from this work-compound's Vicar. She could see the large bean-shaped object attached behind his ear, scaled and reddish green, and looking alive as any scole. Now he truly was a member of the Theocracy, in his white uniform with sacred words written down the side and down one leg of it, his higher-status visored breather apparatus, and now his connection to all brothers and his access to all channels of prayer.

Dent was still gasping for breath as the Proctor glanced unconcernedly down at him, then returned his attention to Ulat.

Ulat gestured down at Dent. "He punctured this pond membrane with his pole-grab, Proctor, and did not bother to report it." He pointed to the pond. "Now you see the result."

"You were required to increase the production of squerms, Ulat. This does not look like any increase to me. The Vicar will not be happy," said Volus.

"What can I do?" Ulat whined.

Now Dent slowly began to breathe more easily, as his scole recovered from the blow it had received.

"You can begin by keeping your workers in order. Those of the Hierarchy are not best pleased by the shortfall of trade essence, so their displeasure is focused on the Deacon, the Deacon's displeasure is focused on his vicars, and theirs on us proctors. We have been instructed to take measures. So must I take measures now, or will you get this mess cleaned up!"

Ulat whirled on his workers. "You four, get in there and clear out those deaders!" He kicked Dent until the man stood up, then gave him a shove towards the pond. Eldene caught Dent's arm before he stumbled into it, and got a brief nod of gratitude before he stooped to retrieve his net and pole-grab.

"Work the edge for a moment," Eldene whispered to him, before leaving her own pole and net on the bank and following Fethan into the turbid water. Dent moved off along one side and began using his pole to pull out all those deaders he could reach.

It was back-breaking and dangerous work. Twice Eldene felt the brush of feeding hooks close to her face, as she and Fethan stooped to lift the tricone from the water and carry it to the bank, before returning with their nets to scoop up the swiftly decaying segments of squerm. Cathol, fourth member of their group, swore quietly, and Eldene noticed that he had not been so swift and had lost a piece of his cheek to one of the creatures. The man continued working, though, blood soaking into the collar of his coverall and dripping into the water. After a short time, Volus departed in his aerofan, leaving Ulat nervously patrolling the bank. Hours later, when the team had cleared the pond of deaders, and were mounding them on the bank for collection, the Proctor returned.

"Come here, all of you!" Volus bellowed.

The four workers gathered before him, with Ulat standing at their backs.

"You have done well, brothers, in your labour for the Church of Masada," said the Proctor, strolling along their line. "But it is a shame that it has even been necessary for you to labour like this." He came to stand before Dent, and gestured Ulat to come and stand beside him.
