'An homage to the nineteen-eighties Lateinos and Romlith building,' said Mr Shadow. 'The names of the blessed running up and down in liquid quartz lettering. And it will have constantly moving scenic lifts and a burger franchise at the base. Selling sprout burgers for vegetarians. Was your girlfriend vegetarian, by the way?'

'Aaaaaagh!' went Derek.

'Oh and there's a message for you,' said Mr Speedy. 'From your business associate Mr Leo Felix.'

Derek ended his Aaaaaagh! with a groan.

'He said, and I quote, "Tell Babylon to get his ass down to me showrooms, I an' I got de crad barges in."'

'Chop chop then,' said Mr Shadow. 'Pacey pacey. The devil makes work for idle hands. And things of that nature, generally.'

'But Kelly. But… Oh God.'

'Have you reported her missing to the police?'

'Yes but…"

'Yes but then that's all you can do. Off to work with you now.'

'I'll need some more money,' said Derek. The words just came out of his mouth. 'Quite a lot more money.'

'Would that be for the holographic Griffin?' asked Mr Speedy. 'The one that failed to appear at three p.m. yesterday?'

'Yes, that's it,' lied Derek. 'And the electric cable for the perimeter fence and the giant feral tomcat and…'

Mr Speedy took out a wad of money notes. 'Ten thousand,' he said. 'Your last. If you foul up, Derek, it will be prison for you.'

'My bitch,' sniggered Mr Shadow.

'What?' went Derek.

'CCTV,' said Mr Shadow. 'Mute Corp run all the police-station circuits. Now get on your way and make things happen.'

Derek got off on his way.

As to actually making things happen…

Well…

'What are those!' asked Derek.

'Crad barges,' said Leo.

'Houseboats,' said Derek.

'Crad barges,' said Leo.

'Houseboats,' said Derek.

'House barges?' said Leo. 'Where de travellin' crad men lived.'

'No,' said Derek. 'No.'

'Listen, Babylon,' said Leo. 'You ever seen a crad barge?'

Derek scratched at his fretful head. 'Well, no,' he said. 'Not as such.'

'An' yo know anyone who ever seen a crad barge?'

'Possibly Old Pete,' said Derek.

'Old Pete an old friend of I an' I,' said Leo. 'Old Pete tell you Babylon, dese are crad barges. Yo have a problem wid dis?'

Derek shook his fretful head. 'No,' he said. 'Stuff it. They look like crad barges to me.'

'Dere,' said Leo. 'Dat not too painful. Yo want to see the steam train?'

Derek shrugged. 'Why not?' he said. 'It can't be any worse than the crad barges.'

Leo drew Derek's attention to the low-loader parked before the showrooms. The low-loader hadn't failed to draw Derek's attention when he had entered Leo's forecourt. It was not the kind of thing you could miss, it being so huge and all.

On the low-loader was something rather big and something all covered by tarpaulins.

Leo began to tug at ropes and unfasten hawsers and unclip those springy things that nearly have your eye out every time you use them to fasten the hatchback of your car to the bumper, because you've just bought something far too big from the DIY store and it's the only way of getting it home without paying the delivery charge.

'Damn,' said Leo, dodging his dreads about. 'Damn ting nearly had I an' I's eye out.'

Leo tugged upon the tarpaulin and Derek joined him in the tugging. Tug tug tug went Leo and Derek.

Fall away and expose to the world, went the tarpaulin and.

'Oh,' went Derek. 'Oh my God!'

'Pretty damn good, eh?' said Leo.

Derek, all flappy jaw, made his head go nod nod nod.

'It's a…'

'Steam train,' said Leo.

'No,' said Derek. 'It's the…'

'Steam train,' said Leo.

'Yes but

'Listen,' said Leo. 'Dis a goddam steam train. Don't go tellin' I an' I it ain't.'

'It is,' said Derek. 'It is. But it's the Flying Scotsman.'

'Don't talk silly,' said Leo. 'Dere ain't no Flying Scotchmen. I seen a housefly. I seen a horsefly. But I tink I see'd about everythin' when I see a Scotchman fly.'

'Stop singing,' said Derek. 'That isn't funny. Where did you get this from?'

'Yo said, no questions asked.'

'The Science Museum?' said Derek. 'Or the National Railway Museum? Or…'

'It de property now of de Brentford Folk Museum,' said Leo. 'And it won't be the Flyin' Scotchman tomorrow. It be de Brentford Flyer. I an' I had me mate Cecil knock up a couple of new nameplates.'

'Doomed,' said Derek. 'I'm doomed.'

'We all doomed, Babylon,' said Leo. 'It just dat some of us more doomed than others.'

Derek didn't stay around to view any more of Leo's acquisitions. And Leo told him that he wouldn't be able to acquire the five miles of perimeter fence until the following evening, so if Derek wanted it putting up 'all around de goddam borough, yo can't fool me, Babylon', Derek was going to have to have his whistling Mute Corp employees working all through the night to get it up before Monday morning. So if Derek was leaving anyway, he'd best get on his way and make things happen.

Derek returned to the police station. The police station was closed for renovations. A sign upon the door instructed callers to post details of missing persons through the letter box, but to mind the wet paint.

Derek didn't mind the wet paint and got some on his sleeve.

Derek wandered off across Brentford. He was in a real state now. He'd quit the job. He would. He'd run. He would, he'd run. He had ten thousand pounds in his pocket. But Derek ached, inside and out. He wouldn't run. He might quit, but he wouldn't run. He couldn't run. He had to find Kelly. He had to find her, but he didn't know how.

He didn't know what to do.

'I know what to do,' said Derek, suddenly knowing what to do. 'No I don't,' said Derek, realizing that in fact, he didn't.

It was very busy busy, all around the streets of Brentford. Very busy busy, with a lot of whistling.

Derek went back to Mrs Gormenghast's.

Mrs Gormenghast drove him away with a big stout stick she had lately acquired, 'in case'.

Derek returned to the offices of the Brentford Mercury. He brought Mr Speedy and Mr Shadow good news regarding crad barges and a steam, train called the Brentford Flyer and of five miles of perimeter fence that would be arriving after midnight of the following day, in one big roll which, according to Leo, could then be picked up from his forecourt. The thought of just how big a five-mile roll of perimeter fence might be was far too much for Derek, who had enough things on his mind to be going on with anyway.

'Brentford Griffin?' asked Mr Speedy. 'Don't forget that.'

'It's all under control,' said Derek, in a manner that suggested that it was.

'Well, keep us informed,' said Mr Speedy. 'You don't have to keep coming back here, just call us on your mobile.'

Derek chewed upon his lip, remembering Kelly's note. 'I'd prefer to speak to you in person,' he said. 'But I will be very busy for the rest of today and most of tomorrow. So I won't be in, so don't dock me any more pay, please.'

'Any news of your missing girlfriend?' asked Mr Speedy.

'No,' said Derek. 'None.'

'You didn't tell us her name.'

'It's Kelly Anna Sirjan,' said Derek. 'But please don't put her name up on your memorial yet. I'm sure she'll be back. I'm sure.'

'Kelly Anna Sirjan,' said Mr Speedy. And he exchanged glances with Mr Shadow.

'Why are you exchanging glances?' Derek asked.

'Oh, no reason,' said Mr Speedy. 'You just go off about the company's business. We'll see you when we see you.'

Derek clutched at his stomach. All the worry was making him feel very sick. 'Goodbye,' said Derek. 'I'll see you when I see you.'
