'Yeah,' said Captain Florence, her crafty little eyes lighting up at this suggestion.

'Exactly,' smiled the Doctor. 'So you think they're going to let you walk away?'

'What you mean?' asked Captain Florence. 'They're 'on'rable men, our clients.'

'So honourable they hired pirates to do their dirty work!' said Martha. Captain Florence leered at her.

'We're not pirates,' she said. 'We're independent financial wotsits.'

'You mean you're venture capitalists?' said the Doctor.

'Yeah,' said Captain Florence.

'Entrepreneurs?' asked Martha.

'Yeah,' said Captain Florence.

'Saps?' suggested the Doctor.

'Huh?' said Captain Florence.

'You're saps, stooges and patsies,' said the Doctor. 'They've got you doing their dirty work and you think that they'll be grateful!'

'Don't you get it?' added Martha. 'They hired you because you're nothing to them. Nothing at all. You've been taken for a ride.'

Stanley, the badger who'd brought Martha aboard and who still lay on the floor in the corner where Captain Florence had hit him, sat up. 'Does that mean,' he said, 'we won't get paid?'

'I assume you got half in advance,' said the Doctor. 'It might be better just to cut your losses and run.'

'Nah,' said Captain Florence.

'Nah, you're not going to run?' asked the Doctor. 'Or nah, you didn't get any money in advance? No don't tell me, I think I already know.'

Captain Florence didn't say anything. Instead she charged at him. The Doctor ducked under her, caught her hairy arm and tossed her lightly over his shoulder. She crashed into the floor, her high-heeled boot smacking into Stanley where he lay.

'Temper, temper,' said the Doctor.

Badgers rushed from behind the hanging silks, but they did not come to apprehend the Doctor. Instead, they gathered in a circle around the Doctor and the captain, all eager to see the fight. It was, thought Martha, like the fights that boys used to have at school. She hurried over to focelyn, their only other ally. Jocelyn's captors seemed to have forgotten her in the excitement.

Captain Florence got to her feet. She reached for the gun at her belt but it had gone. She looked up to see the Doctor holding it, as if he were surprised to find it in his hands.

'Oops,' he said.

'You gonna shoot me?' asked Captain Florence defiantly.

'Nah,' said the Doctor. 'You've got to have some other way for resolving disputes like this. Haven't you?' Martha suspected that the badgers did just sort out their arguments by shooting one another.

'We duel,' said Captain Florence. She slid a short, jagged dagger from her belt. 'Can you duel?'

'I expect so,' said the Doctor. And to Martha's amazement he withdrew a matching dagger from the pocket of his suit jacket. 'Took this from Dashiel earlier,' he said. 'Think it's what he would have wanted.' He handed the captain's gun to one of the other badgers.

Captain Florence lunged at him with her dagger. The Doctor dodged, light on his feet like a well-practised wrestler. Captain Florence lunged again, and again she missed.

'Martha,' said the Doctor, enjoying himself but never for an instant taking his eyes off the captain. 'Did I ever take you back to Roman-era Egypt?'

'Er,' said Martha. 'Don't think so.'

'Well,' said the Doctor, dancing nimbly around Captain Florence, making her do all the work. 'When I'm finished here, that's where we should go.'

'Yeah, all right,' said Martha. She glanced round. The badgers watched in rapt silence. The Doctor's quick and nimble movements simply made their captain seem old and slow and stupid. Again, Martha could see their badger brains struggling to make sense of this challenge to everything they'd been brought up to believe. The kind of reaction most people had when they'd spent five minutes with the Doctor.

'Thing is,' said the Doctor, still moving around inside the ring of wide-eyed onlookers, 'you should spend a day with the captain of Cleopatra's guard. Taught me all my best moves. And won a medal at the Olympics.' He ducked under Captain Florence's arm as she struck out at him, rolling expertly and leaping back on to his feet. A few of the badgers applauded. Captain Florence glared at them and charged at the Doctor again.

'Oh, very good,' said the Doctor, catching Captain Florence's arm in his, sticking out a leg and tripping her over it. 'You nearly had me there.' The badgers cheered – more than half of them now on the Doctor's side. Jocelyn nudged Martha in the ribs.

'You fancy the Doctor!' she grinned.

'I do not!' Martha protested.

'S'OK,' said Jocelyn. 'I do a bit 'an all.'

Captain Florence and the Doctor faced each other. The Doctor stood tall, calm, his hair hardly even ruffled. The captain bent forward, breathing fast and raggedly, her bristly fur glimmering with sweat. She looked exhausted, and it wasn't just the fight. Martha could see her struggling to cope with being so openly challenged, and the Doctor not showing one iota of fear. It was wearing her down. Martha almost felt sorry for her.

'Tell me if you're getting bored with this,' the Doctor said to Captain Florence. 'And we can do something else.'

'Varmint!' roared Captain Florence and charged at him. They grappled, their arms locked together, the captain's jagged dagger just inches from the Doctor's face. He struggled to resist, pushing and twisting to gain purchase, but she clearly had the weight and strength advantage.

Slowly, slowly, the captain forced the dagger closer to the Doctor. Jocelyn grabbed hold of Martha in her excitement and horror. The Doctor strained, gritting his teeth and he struggled to fend off the knife that almost touched him.

And then he suddenly stopped trying. He fell back onto the floor and Captain Florence, who'd been pressing so hard against him, toppled over too. The Doctor rolled quickly out the way and the captain crashed hard into the ground. She let out a terrible cry of pain, making all those watching flinch. The Doctor got to his feet, the dagger still in his hand.

'Don't we stop for orange squash at some point?' he said, not quite as lightly as before. He wiped the sweat from his forehead on the back of his sleeve.

Some of the badgers gasped. Martha turned to look as Captain Florence rolled roughly over onto her back. The captain grunted, struggled to catch her breath. Her own dagger protruded from her chest, the collar) ess blouse she wore already stained with blood.

The Doctor ran forward. 'I can help,' he said. But she slapped him hard with the back of her paw and sent him reeling backwards. He lay, amazed, his hand up to his cheek.

Captain Florence got unsteadily to her feet. She shook off the badgers trying to assist her. Martha could see the dagger had gone in deep. And that there was little any of them would be able to do to save her.

'You win the duel,' said Captain Florence, her voice rough and ragged with exertion.

'Let's call it a draw,' said the Doctor from where he lay.

'Hah,' said Captain Florence. 'Good plan.' And she lunged for one of the badgers stood beside her, and snatched her heavy gun.

'Thanks Isobel,' said the captain.

'Er,' said Isobel, terrified. 'S'OK.'

Captain Florence jabbed the gun towards the Doctor, her eyelids flickering as she fought to stay conscious. 'You can live,' she told the Doctor, 'if you come 'ere an' kiss my boots.'

The Doctor gaped at her. He straightened his tie, then looked up at Martha.

'Do it,' Martha told him. 'Please.'

He grinned at her. 'What time do you make it?' he asked.

The question completely threw her. 'What?' she said. 'Doctor, she'll kill you!'

'Oh yeah,' said the Doctor. 'She'll probably do it anyway. I just wanted to know the time.'

Despite everything, Martha glanced down at her watch. 'Nearly half four in the morning,' she said.
