A bonfire burned on the road, and the hymn-singers had to divert to pass it by. An abandoned house was being looted by a pair of Saxons, a rougher sort than the mercenary warriors who accompanied the refugees. The looters evidently weren’t having much luck. They hurled old clothes and broken furniture out of the house and onto the fire - and books, rolled-up scrolls of parchment and scraped leather and heaps of wooden leaves that curled and popped as they blackened. Most of the pilgrims passed by this scene with eyes averted.

But one old man, his toga flapping about his skinny frame, broke from the column and tried to get the books off the Saxons. His cries were a broken mixture of British and Latin: ‘Oh, you pagan brutes, you illiterate barbarians, must you even destroy our books?’ A young woman called him back, but friends held her.

The two looters watched the old man’s ranting, bemused. Then they decided to have a little fun. They pushed the old man to the dusty ground, picked him up by his scrawny legs and arms, and stretched him out like a pig on a spit. The filthy toga fell away from the old man’s body in loops of cloth, revealing a grubby tunic and a kind of loincloth.

The young woman yelled at the hired warriors to do something about it, but they just shrugged. The old man had provoked the looters; it was his own affair. Even the bishop marched on, singing his hymns lustily, as if nothing was happening.

Now the looters lifted the old man up and held him over the fire. The flames from the burning books licked at the loose toga cloth, and the old man’s yells turned to pained whimpers.

Wuffa glanced at Ulf. ‘They will kill him.’

‘It’s not our affair,’ Ulf said.

‘No, it isn’t.’

‘I’ll take the one on the left. If you can get the old man—’

‘Let’s go.’

The two of them sprinted at the looters. Ulf lowered his massive shoulders and clattered into the man on the left. The old man would have fallen into the flames, but Wuffa leapt over the bonfire, scooped up the old man in his arms, and dropped him to the ground. Wuffa knew the second looter would be on him in a flash, so he bunched his fist and swung it even as he turned. Knuckles smashed into skull with a thud that made Wuffa’s whole arm ache, and the man was knocked sprawling.

Wuffa sat on the man, snatched a knife from his belt and pressed it to the Saxon’s neck. The looter, dazed and enraged, was heavier and stronger than Wuffa. But when Wuffa nicked his throat with the blade he submitted and fell back, panting.
