They crossed the fork and continued on to Work Road. Past the north Dosii guardhouse was Sinker Lake, a deep pool of turquoise-coloured water stretching all the way to the north pit wall. It was said the water was cursed and to dive into it was to disappear. Some believed a demon lived in its depths. Heboric asserted that the lack of buoyancy was a quality of the lime-saturated water itself. In any case, few slaves were foolish enough to try an escape in that direction, for the pit wall was as sheer on the north side as it was on the others, forever weeping water over a skin of deposits that glimmered like wet, polished bone.

Heboric had asked Felisin to keep an eye on Sinker Lake’s water level in any case, now that the dry season had come, and as they walked Work Road, she studied the far side as best she could in the dim light. A line of crust was visible a hand’s span above the surface. The news would please him, though she had no idea why. The notion of escape was absurd. Beyond the pit was lifeless desert and withered rock, with no drinkable water in any direction for days. Those slaves who somehow made it up to the pit edge, and then eluded the patrols on Beetle Road, the track that surrounded the pit, had left their bones in the desert’s red sands. Few got that far, and the spikes named Salvation Row on the sheer wall of the Tower at Rust Ramp displayed their failure for all to see. Not a week went past without a new victim appearing on the Tower wall. Most died before the first day was through, but some lingered longer.

Work Road ran its worn cobbles past Bula’s Inn on the right and the row of brothels on the left before opening out into Rathole Round. In the round’s centre rose Sawark’s Keep, a hexagonal tower of cut limestone three storeys high. Only Beneth among all the slaves had ever been inside.

Twelve thousand slaves lived in Skullcup, the vast mining pit thirty leagues north of the island’s lone city on the south coast, Dosin Pali. In addition to them and the three hundred guards there were locals: prostitutes for the brothels, serving staff for Bula’s Inn and the gambling halls, a caste of servants who had bound their lives and the lives of their families to the Malazan soldiery, hawkers for the struggling market that filled Rathole Round on Rest Day, and a scattering of the banished, the destitute and the lost who’d chosen a pit town over the rotting alleyways of Dosin Pali.

‘The stew will be cold,’ Beneth muttered as they approached Bula’s Inn.

Felisin wiped sweat from her brow. ‘That will be a relief.’
