The Doctor played louder, and over by the door Colin opened his eyes and smiled faintly at the sound of the rallying song of the Jacobite army.

'All right,' said the soldier, 'we'll see if a touch of this bayonet will hush ye.' He turned and ran towards the staircase leading down to the cell.

The Doctor immediately stopped playing and pa.s.sed Jamie back his pipe. 'I think this is yours,' he said.

A moment later, the long bolts rattled back and the door was flung open. The sentry glared around at them. 'Who's responsible for this?' he cried.

The Doctor immediately stepped forward. To Ben's surprise he was putting on his German accent again.

'Ach, himmel,' he said, 'did you hear that tune?'

The sentry nodded suspiciously. 'The rebel dirge.' He looked at the Doctor. 'And you were playing it.'

'Ach, vein. They were playing it. To drive me out of my mind.' He placed his hand on his heart. 'I am from Hanover, a loyal subject of King George the Second.'

The sentry scowled at him suspiciously. 'What's that to do with me?'

The Doctor looked back at the others. Ben realised that the Doctor was up to some ruse, but Jamie was completely outraged by this latest switch in the Doctor's shifting loyalties.

'They know the plan to murder your general, the Duke of c.u.mberland,' said the Doctor.

'That's a lie!' Jamie burst out. Jamie turned round to Colin who was now sitting up and taking notice. 'I knew he was no one of us,' he said.

'Well,' said the sentry truculently, still looking rather suspiciously at the Doctor.

'Take me to Commissioner Grey, and let us hope we may be in time to stop it.'

'Why did you not speak before?' said the sentry, still suspicious.

'Ach,' said the Doctor, ''tis just discovered.' He pointed at Jamie. 'And that rogue is a party to it.'

This was too much for Jamie. He flung himself forward to throttle the Doctor, but the sentry intercepted him with a bayonet levelled at his chest. 'Ye filthy spy, ye,' said Jamie, furious.

Ben grabbed hold of Jamie's arm and pulled him back.

This finally convinced the sentry that the Doctor was sincere: Jamie's anger was too intense to be anything but the real thing. He nodded behind him. 'Go on,' he said, 'out!'

The Doctor gave a quick wink at Ben, and then walked out of the door. The sentry backed out and slammed the door behind them.

Ben nodded approvingly at Jamie. 'Well done, mate,' he said.

Jamie was still furious. 'What d'you mean, and why dinna ye join your friend with the other traitors?'

'Aw, calm down,' said Ben. 'Can't you see it was all a fiddle?'

'Fiddle?' said Jamie.

'Trick, mate. A ruse, to get us out of here.'

Jamie shook his head, trying to comprehend. 'I dinna understand ye.'

Ben shook his head, then patiently tried to explain.

'Blimey, listen. Outside, he's got a chance to get away and get help, to rescue us. What chance do you think he's got paddling around in here?' He looked down to where the water was now lapping around their feet.

Jamie finally seemed to comprehend what Ben was saying. 'Aye,' he said, 'I see. But nevertheless, I'm a'

worriet.'

Ben looked around the cell. 'Well, don't waste time worrying about the Doctor, mate. Worry about us.' He pointed up to a dark line which ran all the way around the circular cell. 'That's a tide mark, unless I'm very much mistaken.' He bent down and tasted the water. 'Yeah, salt.

'Ere,' he touched the mark which was some foot above their heads. 'That's where the water level comes up to when the tide's in, and it ain't my bath night.'

8.

Blackmail In the lantern light, Polly was carefully counting out Algernon's money. 'Eighteen, nineteen, twenty guineas.

Hmm... how far will that get us, do you think?'

Kirsty, beside her, was wide-eyed. 'I've never seen so much money in all my days,' she said.

'You'll both h-hang for this, you know,' said Algernon.

Polly turned to him. 'You're very fond of hanging, Mr uh-h-h...' She had an idea. 'Here, what is your name?'

Algernon set his mouth and turned his face away. 'I refuse to tell you.'

'Oh, we're very brave all of a sudden, aren't we?' said Polly. She turned to Kirsty. 'He must have some identification on him. Let's find it.' Polly leaned forward and unb.u.t.toned the top of Algernon's waistcoat.

Underneath, there was a large crescent-shaped ident.i.ty disc, worn by all the British soldiers of that period. She pulled it out towards the light and read, 'Algernon Thomas Alfred Ff she stumbled for a moment on his surname 'Ffinch. With two "f"s yet? A Lieutenant in the Honourable Colonel Atwood's Rifles.' She laughed. 'I'll bet the Honourable Colonel Atwood would be interested to hear how one of his lieutenants was captured by two weak girls.'

For the first time, Algernon's eyes widened in fear. 'Oh come,' he said, 'surely you would not tell...'

Polly smiled at him. 'Oh, wouldn't we, Algernon.' She turned to Kirsty. 'Give me that knife.'

Kirsty handed over the dirk.

Algernon braced himself. 'What are you going to do?' he said.

'Never fear, Algernon Thomas Alfred,' said Polly. She cut off a lock of his hair protruding from under the dishevelled white wig. 'You know,' said Polly, 'how girls like souvenirs of their fellows.' She looked at him. 'Well, perhaps you don't, but I'm just after a small souvenir of you. There.' She then raised the dirk and cut the cord that held the ident.i.ty disc. 'This hair should be proof enough that we captured you. Just in case the Colonel doesn't believe us.'

Kirsty had been watching this with astonishment. 'But why would you be...'

Polly turned to her. 'We may need an ally in the enemy camp.' She looked back at the unhappy Algernon. 'And I think we've found one.' She nudged him with the dirk.

'Right, Algernon?'

'It's sheer b-b-blackmail,' sputtered Algernon.

'You got that one right,' said Polly, 'that's what it is.'

She turned. 'Come on, Kirsty, we'd better get out of here before his men get back. Sit up, Algy dear.' Polly helped Algernon to a sitting position then, standing lightly on his knee and shoulder, she swung herself gracefully over the top of the pit, then turned and helped Kirsty out the same way.

She looked down at Algernon. 'Don't worry, they won't be long, I'm sure. And we'll be looking out for you in Inverness. Don't forget.'

The last thing Algernon heard was Polly's light laugh rippling back as the two girls scampered away down the hillside.

The Sea Eagle was one of the finest inns in the town of Inverness. It had been built largely for the occupying English soldiers who had one of their main fortresses at Inverness, and was a large handsome timbered building, unlike the low thick-walled cottages that usually pa.s.sed for inns in the highlands of Scotland.

Solicitor Grey, his clerk Perkins, and a heavily-built ruffian in seaman's clothes, Henry Trask, was with them.

Captain Trask, as he styled himself, was master of the brig Annabelle Annabelle. A one-time pirate gunrunner and smuggler, Trask's hard nature showed on his face. It was deeply lined with a livid scar running across the forehead, and pock-marked with a blue powder mark left by the unpredictable guns of the period which often blew up in a man's face.

Right now, Trask, who'd obviously been drinking there was an empty wine bottle on its side in front of him, and a full flagon at his lips was in a raucous good humour. 'Well, lawyer,' he said, 'my old cattleboat's ready for its livestock. Eh?' He roared with laughter, and Perkins beside him gave a mild, conciliatory t.i.tter in reply. The half-drunk Trask, always quick to take offence, stopped laughing immediately and glared at him. 'Belay there.'

Perkins's laugh cut off abruptly. 'What in thunder do you think you're laughing at?'

'N-n-nothing,' said Perkins, beginning to stammer nervously. But Grey leaned across the table, his face serious.

'It won't be a laughing matter for any of us if we are caught, I a.s.sure you. That is why we must start loading the prisoners tonight.'

Beside him, Perkins, relieved to have Trask's attention diverted, nodded and repeated Grey's last words. 'Yes, tonight,' he said.

'By the time the King's judges are ready to try the rebels, we shall have them safely on the plantations,'

continued Grey.

Trask leaned forward, nodding his great head. 'Aye,' he said. 'A Highlander will do twice the work of one of your black slaves.'

Perkins smirked. 'At least twice,' he said.

Trask immediately turned on him. 'Who asked for your opinion?'

Perkins, snubbed again, shrank back from the fearsome-looking captain, but Grey interposed and rapped the table with his snuffbox. 'Silence, Captain,' he said. 'I won't have my clerk bullied in this way.'

Then as Trask scowled in his direction, he leaned forward, his eyes searching the seaman's face. 'I have enough evidence on you to send you to the gallows ten times over. Don't forget it.'

For a moment Trask rose in his chair and seemed about to throttle the quiet-spoken lawyer. Then, the steely intensity of the solicitor's unflinching gaze made him uneasy and he slumped back, dropping his eyes and reaching for the wine flagon.

There was a knock at the door. 'Come in,' Grey called.

The door opened and the sentry stuck his head round.

'Well?' said Grey.

'It's one of the prisoners, Sir. He insists on seeing you.

Says he's got some special information about a plot on the Duke's life.'

'Why come to me?'

'He won't talk to anyone but you, Sir,' said the sentry.

'Which prisoner is it?' said Grey.

'The German doctor, Sir.'

Grey looked puzzled for a moment, and then his face cleared. 'Ah, interesting,' he said. 'Bring him up to me at once.'

The sentry saluted, but made no move to go.

'Well man, what are you waiting for?' Still the sentry stood there immobile, his eyes staring straight ahead.

'Ahh,' Grey sighed and turned to his clerk. 'Perkins,' he said.

Perkins rather reluctantly felt in his waistcoat pocket and brought out two coins. He selected the smaller and gave it to the sentry. The sentry took it and looked at it for a moment in disgust, then exited.

Grey turned back to Trask. 'Now, Captain,' he continued, 'I suggest you start loading the prisoners.' He turned to a small leather case beside him on the table, opened it and brought out an imposing-looking parchment doc.u.ment with ribbons and large seals attached. 'Here is your warrant. To save comment, bring them through the back way.' The door opened, and the Doctor entered, followed by the sentry. Grey looked back at the Captain.

'Right, and you go with him, Perkins.' Trask nodded, rose and, followed by Perkins, walked to the door, watched carefully by the Doctor.

Grey opened the leather case once more and brought out a small, silver-mounted flintlock pistol. He looked at it for a moment and then put it down on the table in front of him, then nodded to the sentry. 'You may go, man.' The sentry saluted and left the room. Grey turned back to the Doctor.

'Now Doctor,' he said. 'Your story. Let us hope it is an entertaining one. It cost me a silver shilling. What is the nature of this plot?'

The Doctor looked at him for a moment and then shrugged and started picking his teeth. 'There is no plot,'

he said carelessly.

For a moment Grey looked surprised, then his face darkened. 'Be careful, Doctor, how you waste my time. I can have every inch of skin flayed off your back just by a snap of my fingers.'

The Doctor held his hand up and started examining his nails, speaking casually over his shoulder. 'Would the chance to lay hands on 15,000 be a waste of your time?'
