Queen of the Night

Introduction
    During the trial of Christ, Pilate, according to the gospels, wanted to free the prisoner. He was stopped by a cry that if he did so he would be no friend of Caesar's. According to commentators, Pilate recognised the threat. Every Roman governor and official was closely scrutinised by secret agents of the Emperor, 'the Agentes in Rebus', literally 'the Doers of Things'! The Roman Empire had a police force, both military and civil, though these differed from region to region, but it would be inaccurate to claim the Empire had anything akin to detectives or our own CID. Instead, the Emperor and his leading politicians paid vast sums to informers and spies. These were often difficult to control; as Walsingham, Elizabeth I's master spy, once wryly remarked, 'He wasn't too sure who his own men were working for, himself or the opposition.'
    The Agentes in Rebus were a class apart amongst this horde of gossip-collectors, tale-bearers and, sometimes, very dangerous informers. The emperors used them, and their testimony could mean the end of a promising career. This certainly applied to the bloody and byzantine period at the beginning of the fourth century ad.
    The Emperor Diocletian had divided the Empire into East and West. Each division had its own emperor, and a lieutenant, who took the title of Caesar. The Empire was facing economic problems and barbarian incursions. Its state religion was threatened by the thriving Christian Church, which was making its presence felt in all provinces at every level of society.
    In ad 312 a young general, Constantine, supported by his mother Helena, a British-born woman who was already flirting with the Christian Church, decided to make his bid for the Empire of the West. He marched down Italy and met his rival Maxentius at the Milvian Bridge. According to Eusebius, Constantine's biographer, the would-be Emperor saw a vision of the cross underneath the words 'In hoc signo vinces' ('In this sign you will conquer'). Constantine, the story goes, told his troops to adopt the Christian symbol and won an outstanding victory. He defeated and killed Maxentius and marched into Rome. Constantine was now Emperor of the West, his only rival Licinius, who ruled the eastern empire. Constantine, heavily influenced by his mother, grasped the reins of government and began to negotiate with the Christian Church to end centuries of persecution. Nevertheless, intrigue and murder still held sway. There was unfinished business in Rome and the Agentes in Rebus had their hands full… Helena favoured the Christian Church but soon realised that intrigue, robbery and murder were no respec-tors of emperor or priest.

    The tribesmen, the Picti, slipped through the summer darkness to gather in the pitch-black copse of trees. They had already visited the sacred stones on the summit of the Hill of Sacrifice a few miles further north, where their priest had made the blood offering, the heart of the Roman scout caught earlier in the day. They had watched the man, eyes drugged, face slack, being stripped, bound and laid on the altar stone. The high priest's obsidian knife had flashed in the setting sun and fell just as their chanting reached its climax. Afterwards the chieftain had massed the entire war band and they had swarmed here to recover what was theirs – or rather his – by right: the Golden Maid, taken by the Men of Iron, the Crested Ones, who hid behind their wall of stone. The chieftain, so determined on vengeance, had even brought his only son, a mere boy, the sacred insignia etched on his thigh, to his first blooding. The boy was now a member of the war band, hair plaited, face and body daubed in war paint.
    The Picti stared out at the brooding, crenellated wall of the fortress, the house of the Crested Ones, the Romani, with their body armour and eagle standards. The war band had attacked two days previously, bringing up specially prepared ladders, but had been beaten back, so they'd watched and waited. The chieftain had begun to wonder about the stories that had come whispering like the wind across the heather. How the Crested Ones were fighting amongst themselves, weakening their defences along the Great Wall, an abrupt change from a month ago when the Romani had launched their own raid and captured the Golden Maid. Since then, nothing but silence except for that solitary scout. The
