'You mind telling me what I'm listening for?'
'I heard a scream.'
'A scream? Up here in the mountains? Sure it wasn't the wind?'
'I'm positive.'
'Maybe some bacchanalian revelry of the mountain folks then.'
'Quiet! There it is!'
This time Macro did hear the sound: unmistakably human and carrying with it a clear sense of torment and agony. The scream was abruptly cut off, and Macro felt the hairs rise on the back of his neck.
'Shit. You're right.'
'What should we do?'
Macro threw back his blanket and groped for his boots. 'Check it out, of course. Come on. Bring your sword.'
'What about Minucius?'
'Leave him. I'm not going to look like some jumpy recruit. We'll just check it out and come back for help if we need it. Let's go.'
As they emerged from the tent they saw that the snow had stopped falling, and a thick blanket of white covered all the tents and the wagons. A pair of sentries stood watch at each end of the camp site and stamped their feet to keep them from going numb. The wind had died down to a flukey breeze, and overhead thin shreds of silvery cloud flitted across the bright points of star constellations.
'This way,' Macro said quietly, and softly crunched through the snow towards the nearest sentry. The man stiffened as he noticed the officers approaching.
'Halt! Advance and be recog-'
'Shut up. If you don't know who we are yet you never will. You're supposed to be keeping watch for people approaching the camp, you dozy bastard, not those moving around inside it.'
'Sorry, sir.'
'It doesn't matter,' Cato cut in.
'Yes, it bloody does,' Macro grumbled.'If he can't keep a decent watch he's no use to anyone, even the marines.'
Cato ignored him and concentrated his attention on the sentry. 'Did you hear anything a moment ago?'
'Hear what, sir?'
'A man's voice, a scream.'
The sentry looked wary. 'I might have.'
'Don't fuck about, son.' Macro poked him in the chest.
'Did you hear something, or didn't you?'
'Yes, sir. But only for a moment. I might have imagined it. Thought it came from over there.' He gestured towards the rising mass of the hill behind the camp site. 'Up the hill, or more likely round the other side, I should think, sir.'
'Why didn't you raise the alarm?'
'For something I might have heard, or imagined, sir?'
'You don't take risks with other people's lives, lad. Understand?'
'Yes, sir. Want me to call out the rest of the men?'
'No,' said Macro. 'We'll investigate. If we're not back by the next change of watch, then you can raise the alarm. It's probably nothing to wet yourself over – just a wolf or something. Now get back on watch.'
The recruit saluted and turned to face away from the camp site.
Macro pointed up the side of the hill. 'That way, I think. Let's go.'
When they were out of earshot of the sentry Cato nudged him. 'A wolf?'
'Might be. I've heard them sound like that before.'
They reached the foot of the slope and waded through a drift until they came to the treeline, where a dense forest stretched up the slope. Very little snow had penetrated the heavy lower branches and the air was thick with the scent of pine. The incline was steep and they had to scrabble up on hands and feet, weaving between the tree trunks, making little sound as their boots trod on generations of dead pine needles. Sheltered from the breeze and warmed by their exertions, they emerged panting and sweating from the far side of the trees. By the loom of the snow they could see that there was a low craggy outcrop above them, and then the crest of the hill. Cato glanced back and saw the camp site some distance below them, hardly recognisable as tents and wagons under a thick blanket of snow. The scream came again, much more distinct this time, and the two centurions looked at each other.
'What do you reckon?' asked Cato.
'Sounds like some poor bastard's being given a hard time of it.' Macro took a deep breath and climbed towards the rocks. Cato followed, stepping into the deep footprints Macro had left in the snow. The rocks were loosely jumbled and there were sufficient handholds and ledges to make it easy going, and moments later Macro lent a hand to Cato and heaved him up on to a flat slab that overlooked the gorge the convoy had wound its way up that afternoon. Below them the road turned round the mass of the hill and rose up the other side.
They both saw the fire at once, a small glittering yellow glow at the edge of the road no more than a hundred paces below them. Four horses were tethered nearby, and the shapes of three men sitting on a fallen tree trunk close to the fire. A fourth was leaning over the end of the tree trunk and an agonised wail carried up the slope. The man stepped back towards the fire and revealed a fifth man, stripped to his waist and bound to the tree trunk. By the wan glow of the fire Macro and Cato could see black marks across his chest. The source of the marks was quickly apparent when the man who had been standing over him moved to the fire and lowered the tip of his sword into the heart of the small blaze.
Cato turned to his friend.'I've seen that man before. The one tied to the tree. He's that merchant.'
'Merchant?'
'The one from Hispellum… What do you think's going on? Who are those men?'
'Not sure. Brigands, most likely. But I'm not going to sit here and let them carry on with that.' Macro looked over the ground and thought for a moment. 'It'd take too long to go back and rouse the others. By the time we got 'em back up here that poor bastard will be finished. Besides, with that bunch of marines on our hands there'd be no question of surprising them. They'd kill him, get on their horses and slip away long before we could get down the slope.'
'I see.' Cato nodded slowly. 'So, what you're saying is that it's down to us.'
'Got it in one, lad.' Macro clapped him on the shoulder. 'Come on.'
They eased themselves down from the rock slab, and then followed the crags along until they came to a thick growth of trees that stretched down to the road, just as the prisoner cried out again.
'Please! Please, no more!' The wail carried clearly up the slope to the two centurions.'I swear I don't know anything!… Please! No!'
A tormented shriek cut through the night, and spurred Macro and Cato on. They moved into the shadows of the trees and half-scrambled, half-slid down beneath the snow-laden boughs of the trees. They kept the fire in sight, and it twinkled through tangled skeins of slender pine branches as they descended. At length Macro stopped and put out an arm to warn Cato that they were close enough. Through the trees, no more than fifty paces away, the four men and their prisoner were clearly visible in the flickering firelight.
Macro drew his sword and took a step forward.
'Wait!' Cato hissed. 'You're not just going to charge in there.'
'What else?' Macro whispered. 'The two of us are hardly going to surround them.'
'No,' Cato muttered. 'We should have gone back for help.'
'Too late for that now.'
'All right then. We'll go in. But let's try and even the odds first. See there.' Cato pointed out a shallow fold in the ground beside the road, and Macro realised that it was the snow-covered drainage ditch. It passed close by the fallen tree trunk, and the men sitting there had their backs to the road.
Macro sheathed his sword and nodded. 'Looks good enough for me.'
They crept down through the trees and when they reached the open ground beside the road, both men crouched low and crunched softly across the snow until they reached the ditch, and then lowered themselves on to their stomachs. With Macro in the lead they cautiously crept forward, fighting back the urge to move more quickly when a fresh chorus of screams cut the air. They passed the edge of the trees, and drew level with the orange hue of the fire.
'Keep down,' Macro whispered over his shoulder. He eased his sword from its scabbard, took a deep breath, and slowly raised his head. Over the lip of the ditch he could see the silhouettes of the three men sitting on the tree trunk. They were silent, just watching the fourth man as he bent over the prisoner, who was invisible from the ditch. Macro mouthed a curse. The fourth man was facing them. He would see them the moment they rose up from the ditch.
