The fight was far from over, but Fabiola sensed that the tide had turned. Fortunately they were still some distance from the bloodshed. The thugs who had marched them to the Forum had disappeared into the melee. It was time to escape, if they could. She jerked her head at Tullius, who was more than happy to obey. He barked an order at the others. Forming a protective diamond shape around Fabiola, the nine bodyguards drew their swords, turned as one and began to beat a path out of the crowd. Thankfully, large numbers were also trying to flee. With their captors’ attention diverted, all the prisoners had a chance to gain their freedom, brutally pushing, shoving and ignoring the weak, who were simply trampled underfoot. When Fabiola bent to help an old woman who had fallen to her knees, Tullius roughly pulled her away. ‘Leave her!’

Shocked at being handled, Fabiola realised the Sicilian was truly worried about her safety. She looked back in anguish, but the lined, terrified face had already been swallowed by the heaving mass. Another innocent victim. But there was no time to grieve or to dwell on the gods’ purpose today. Intent on their own survival as well as that of their mistress, Fabiola’s guards battered on.

‘Make for that!’ Tullius shouted, pointing at the temple of Castor, the nearest building. Ducking their heads down, the bodyguards soon gained momentum.

Fabiola held her breath as they crept through the maelstrom. Occasionally Tullius or the others had to use the hilt of their swords across someone’s head, but most gang members nearby were more interested in attacking the gladiators than stopping a few people moving away from the battle.

Finally reaching the carved stone steps, they worked around their base and into a narrow side street. Fabiola took one more glance at the Forum. The two sides were still fighting hammer and tongs, neither prepared to give or ask for quarter. Milo’s gladiators had been broken up and were now in small groups, struggling for their lives against far superior numbers of plebeians. Any success cost the thugs dearly though: every murmillo or secutor who died was taking three or four men with him. The dead sprawled everywhere now, crushed underfoot, heaped on top of each other, prostrate in the entrances to temples. It was a massacre.

Rome was finally toppling into anarchy, and there was no one to prevent it.

‘Hurry!’ Tullius’ sole concern was to get his mistress to safety.

It was foolish to linger, but Fabiola could not take her eyes off the scene. She watched as six plebeians emerged from the confusion some distance away, bearing Clodius’ body. Led by Fulvia and the bearded leader whom they had encountered earlier, the group moved purposefully towards the Senate entrance. Behind came a pair of men carrying flaming torches. Fabiola gasped. Clodius’ funeral pyre was to be lit inside the Republic’s most important structure: the Senate itself.

Tullius bobbed up and down unhappily, but Fabiola would not budge. And her guess was correct. Moments later, tendrils of smoke began billowing from inside the sacred chamber. No event in the city’s history had ever been more dramatic. Five hundred years of democracy were about to go up in flames.

Even Tullius paused when he realised what they were witnessing. Politics affected slaves little, but certain things in the Republic were permanent – or seemed so. The building that housed the seat of government was one of them. To see the Senate being burned was extraordinarily shocking. If it could be destroyed, then so could any other structure in Rome.

The Sicilian came to his senses at last. ‘We cannot stay, Mistress.’ His tone was firm.

Fabiola sighed in acceptance and meekly followed Tullius away. Jupiter had spared their lives thus far, but they should not tempt fate. It was time to leave, before things got even worse. Only military force could bring back peace now. The senators would have no choice but to ask Pompey, the new consul, to intervene, which would swing the balance of power firmly away from Caesar. Brutus’ position would also be weakened by this unrest. So, therefore, would hers. And what would happen in Gaul? If Vercingetorix’ rebellion succeeded, Caesar’s attempt to become the Republic’s leader would fail completely. A defeated general could never retain the fickle public’s approval. Fabiola steeled her resolve. Jupiter had shown her his favour by letting her escape the chaos. Only a short time earlier, she had been ready to die – well, no longer. No matter what happened, this would not be the end of her rise to power.

Fabiola did not even see the arrow strike. It was the gasp of pain which attracted her attention. She looked up to see Tullius toppling forward, looking faintly surprised. A feathered wooden shaft protruded from the middle of his chest, its iron point buried deep in his lungs. Mortally wounded, the Sicilian landed face down in the ankle-deep mud.

A heartbeat later, another guard followed him. Then a third.

Ducking down, Fabiola spat a bitter curse. How could I have been so stupid? she thought. Jupiter does not bother with the likes of me.

The way ahead had been blocked with piles of refuse, lengths of wood and broken pottery. Eager to get away from the Forum, Tullius had not seen it. Fabiola had not been paying attention either. On another day, she might have thought the waist-high rubbish just indicated a particularly poor street, a place where the inhabitants cared for neither health nor hygiene. Not today.

This was an ambush.

A fourth missile hissed through the air, taking the guard nearest to her through the neck.

They could not go forwards. Or back. Certain death awaited in the Forum. Eyes swivelling, Fabiola looked for the archer.

One of her five remaining followers pointed. Then he screamed, clutching at the arrow jutting from his left eye. Falling to his knees, he tugged frantically at the shaft, and Fabiola heard metal scrape off bone as the barbs pulled free of the socket. His face drenched in blood and aqueous fluid, the brave guard staggered upright, sobbing with pain. Now half-blind, he would be of little use in the impending fight.

From a side alley, ten ruffians emerged. Dressed in ragged, dull brown tunics, they were carrying an assortment of weapons: spears, clubs, knives, rusty swords. There was one bowman, an evil-looking type who smiled as he notched another arrow to his string. His companions were similarly unsavoury in appearance.

‘Look what we’ve got here, boys,’ said a spearman with a leer.

‘A noble lady!’ answered another. ‘Always wanted to try one of those.’

The archer licked his lips. ‘Let’s see what’s under that fine robe.’

The men moved in, their faces filling with lust. This would not just be robbery. Fabiola saw rape and death in their dark eyes. But instead of fear, anger boiled up inside her. These were the lowest of the low: the scum who waited to prey on the weak and unarmed fleeing the battle.

‘Mistress?’ asked her guards in unison. Without Tullius, they were unsure what to do.

She swallowed hard. None had shields, leaving them defenceless against missiles. If they did not act fast, they would all fall to the bowman. There was only one way to overcome their ambushers, who were most probably cowards. Producing the dagger Tullius had given her, Fabiola bared her teeth. ‘Run straight at them,’ she hissed. ‘It’s that, or we go to Hades.’ If this was the end that Jupiter had chosen for her, she would at least die well.

Seeing her determination, the guards’ courage rose. Four raised their swords, and the one-eyed man unsheathed a knife. With his reduced ability to judge depth of field, a short weapon would be easier to fight with. In a heartbeat, the five were lined up beside her. Slaves or not, it was better to die fighting than to just be slain out of hand.
