At last they had hit something. “Is it a box?” he called hopefully down the shaft.

The only response was frantic tugs on the ropes that led down into the eight-foot-deep hole. “They want to come up,” muttered one of the men standing round it.

“Haul away, then.”

Slowly the mud-stained men were dragged up out of the earth. Shef waited with what patience he could for a report.

“Not a box, master. It’s a boat. The bottom of a boat. They must have buried ’un upside down.”

“So break through it.”

Heads shook. Silently, one of the ex-slaves held out his mattock. Another passed a faintly glowing fir-brand. Shef took both. There was no point now, he realized, in asking for further volunteers. He drove the halberd in his hand deep into the ground by its spike, took a rope, tested its anchor-stake, glanced round at the dark figures, only their eyeballs showing in the night.

“Stay by the rope.” Heads nodded. He lowered himself awkwardly, torch and mattock in one hand, into the dark.

At the bottom he found himself standing on gently sloping wood, obviously near the keel. He ran his hand over the planks in the faint torchlight. Overlapping, clinker-built. And, he could feel, heavily tarred. How long might that have lasted in this dry, sandy soil? He lifted the mattock and struck—struck again more firmly, heard the sound of splintering wood.

A rush of air and a foul stench enveloped him. His torch glowed with sudden force. Cries of alarm and scamperings from above. Yet this was not a stench of corruption. More, he felt, like the smell of a cow-byre at winter’s end. He struck again and again, widening the hole. Beneath it, he realized, there was vacancy, not earth. The barrow-builders had succeeded in creating a chamber for the dead, and for the hoard, had not merely left it buried in the ground for him to sift through a shovel at a time.

Shef dropped the rope through the hole he had made and swung himself after it, torch in hand.

His feet crunched on bones. Human bones. He looked down, and felt a wave of pity. The ribs he had snapped were not those of the master of the hoard. They were a woman’s bones. He could see her cloak-brooch glinting below the skull. But she lay facedown, one of a pair, stretched out lengthwise along the floor of the burial chamber. Both women’s spines, he could see now, were snapped, by the great quernstones that must have been hurled down upon them. Their hands had been tied, they had been lowered into the tomb, their backs had been broken and then they had been left to die in the dark. The quernstones showed what they had been and what they were there for: they were the master’s grinding slaves. Here to grind his meal and prepare his porridge into eternity.
