Marcus turned away to head across the forum towards the inn that the soldier had indicated. The owner of the Jolly Boar had set up some tables and benches outside the entrance, and these were crowded with the centurions and optios of Caesar’s cohorts. Threading his way through the soldiers, he could not help wondering what shape they would be in come the morning when it was time to march into the mountains.

From inside, Marcus could hear excited chatter and cheering before there was a brief lull, then a crescendo of noise. He squeezed through the door and saw at once that the inn was a lot bigger than it looked from outside, a single open room stretching back a good hundred feet. A counter was set up in the far comer from where a sweaty-looking old man handed jugs and cups to his servants and kept tally on what each table had consumed. The middle of the room had been cleared and a crowd of tribunes, centurions and civilians stood in a ring over a dice game. Marcus knew that if he drew up his hood he would only attract attention, so instead he worked his way round to an alcove and stood in the shadow as he scrutinized the men in the room.

He picked out Quintus easily enough. Portia’s young husband was grinning like a fool as he opened his purse. But his smile faded as he groped around inside and his hand came out clutching a small handful of silver coins. He hesitated briefly, before bending down to place his bet. Marcus’s eyes then fixed on Festus, sitting on the far side of the room, watching proceedings as he sipped from a bronze goblet. Marcus followed his line of sight to a group of men at a table opposite Festus. He spotted Decimus at once, due to the expensive embroidery on his cloak. A squat muscular man sat next to him, and three more perched on the other side of the table with their backs to Marcus. Two had close-cropped hair; the third was shaven-headed, but the dark hair of an unkempt beard bustled out from each cheek so that he probably looked like a barbarian from the front.

Now that he had them in sight, Marcus stared at Decimus for a while. He recalled vividly the cruel expression in the man’s face when the moneylender had told Marcus and his mother of their fate as they lay in a holding cell of the slave market back in Greece. Marcus edged round the room and made his way towards Festus, where he positioned himself with his back to Decimus and the others.

Festus’s eyebrows rose briefly in surprise. He leaned across the table. ‘What are you doing here?’ he growled.

‘Caesar’s dismissed me for the evening. I thought I’d have a look around the town.’
