It was a spectacular sight but Marcus could not summon up any excitement. He sat in his saddle beside the other riders, surveying the scene from the last rise in the ground before the road reached Ariminum. Three days had passed since their lucky escape in the mountains. The man injured in the leg had been left at Hispellum, the first town they had reached. A Greek surgeon there said he would recover, but would be left with a crippling limp for the rest of his life. It was the loss of Lupus that had hit Marcus hard. He had encountered few people he considered friends since being enslaved, and to lose another was a cruel reminder of his loneliness.

There had been Brixus during his days at the gladiator school in Capua. Then Brixus had discovered Marcus’s identity before escaping from the school to find his former comrades from the Spartacus revolt. And now they too knew that the son of their hero was alive. When Brixus had revealed the truth, it had shaken Marcus’s world to the ground. Titus, the man he thought was his father, and had admired and loved, had been one of the Romans who crushed the slave revolt and killed his real father. It had been hard to accept at first, but since Marcus had learned more about Spartacus his respect for the father he had never known had steadily increased. Respect, but not the affection he had known for Titus. How could it be otherwise?

Then, when he had been brought to Rome, he’d befriended Portia, Caesar’s niece, after saving her life. A few years older than Marcus, she had been sent to Rome to be raised by her uncle while her father campaigned in Hispania. Her loneliness and her gratitude to Marcus had drawn them closer than was usual for the niece of a consul and one of his slaves. However, Marcus had always felt a sense of reserve in her company. There were limits to what a slave could say openly in such circumstances. Marcus was a little nervous at the prospect of meeting her again in Ariminum. She would surely have changed now she was married to Quintus, and might not like reminding of her closeness to one of her uncle’s servants, even though he had been granted his freedom.

His other friends had been the two boys Marcus had shared a cell with in Caesar’s household: Corvus and Lupus. The former had worked in the kitchen, often bitter about the way life had treated him. But he had courage and in the end had given his life to protect Portia. Then there was Lupus. Lupus was a gentle soul who loved his craft and read books too, and even seemed to enjoy them. Now Lupus was gone, and Marcus felt alone again as he grieved for his friend.

‘We’ll make for the camp first,’ Caesar announced, interrupting Marcus’s dark thoughts, ‘before I arrange for accommodation in Ariminum.’

He waved his hand forward and broke into an easy canter to cover the last few miles. The others spurred their mounts and followed him down the road. A short distance from the town gate they turned on to a side road that led towards a wooden bridge over the river. The autumn and winter rains in the Apennines had swollen the river so that it threatened to breach the banks as it rushed past the pylons supporting the bridge.
