Boudica smiled. ‘From my own experience I’d say you Romans are only marginally more discriminating. Must be something they put in all that wine you southern races are so fond of drinking.’

‘You complaining?’ asked Macro, watching Boudica closely.

‘Let’s just say it was an education.’

‘And you’ve learned all you need about the men of Rome, I suppose.’

‘Something like that.’

Macro’s eyes glinted angrily at Boudica, before he returned to his broth and continued eating in silence. An awkward tension filled the air. Cato stirred his broth and brought the conversation back to the less touchy subject of Diomedes.

‘When was the last time she saw him?’

‘Only two days ago.’

Cato stopped stirring.

‘Came through on foot,’ Boudica continued. ‘Just stayed for a meal and passed straight on, heading west into Durotrigan territory. Doubt he’ll find much trade there.’

‘He’s not after trade,’ Cato said quietly. ‘Not any more. Did you hear, sir?’

‘Of course I heard. This bloody mission is dangerous enough as it is, without that Greek stirring things up. Just hope they find him and kill him quickly, before he causes us any trouble.’

They continued eating in silence, and Cato made no further attempt to keep the conversation going. He pondered the implications of the news about Diomedes. It appeared that killing the Druid prisoners was not enough for the Greek. His thirst for revenge was leading him towards the Dark Moon Druids’ heartland. On his own he stood little chance, and he might alert the Durotriges to be on the lookout for strangers. That could only magnify the risk the four of them already faced. Gloomily Cato ate another spoonful of broth, chewing hard at a lump of gristle.

The hospitality of Vellocatus and his wife extended to a silver platter of honeyed cakes when they had eaten their fill of broth. Cato lifted a cake and noticed a geometric pattern on the platter beneath it. He dipped his head to look more closely.

‘More of the Greek’s trading, I imagine,’ said Boudica as she helped herself to a cake. ‘Must be making a fine living out of it’

‘I bet he is,’ said Macro and took a bite of cake. His eyes instantly lit up and he nodded approvingly at their hostess. ‘Good!’

She beamed happily and offered him another.

‘Don’t mind if I do,’ said Macro, spilling crumbs down his tunic. ‘Come on, Cato! Fill up, lad!’

But Cato was lost in thought, staring fixedly at the silver platter, until it was taken away and returned to the wicker basket. He was certain he had seen it before, and was greatly disturbed to see it again. Here, where it had no reason to be. While the others happily ate the cakes, he had to force himself to chew his. He watched Vellocatus and his wife with a growing sense of unease and anxiety.

‘Are you sure they’re asleep?’ whispered Macro.
