Oh… kay.

His hands and arms were numb and yet painful at the same time. He heard the rattle of the big freight elevator inside the building, the thud of a hatch being slapped back, the footsteps across the roof, felt the rope hit his arm.

'Grab it or drop,' said a voice as he flailed to grasp it. 'It's all the same in the long run.' There was laughter in the dark.

The men heaved hard at the rope. The figure dangled in the air, then kicked out and swung back. Glass shattered, just below the guttering, and the rope came up empty. The rescue party turned to one another.

'All right, you two, front and back doors right now!' said a coachman who was faster on the uptake. 'Head him off! Go down in the elevator! The rest of you, we'll squeeze him out, floor by floor!'

As they clattered back down the stairs and ran along the corridor a man in a dressing gown poked his head out of one of the rooms, stared at them in amazement, and then snapped: 'Who the hell are you lot? Go on, get after him!'

'Oh yeah? And who are you?' said an ostler, slowing down and glaring at him.

'He's Mr Moist von Lipwick, he is!' said a coachman at the back. 'He's the Postmaster General!'

'Someone came crashing through the window, landed right between— I mean, nearly landed on me!' shouted the man in the dressing gown. 'He ran off down the corridor! Ten dollars a man if you catch him! And it's Lipwig, actually!'

That would have re-started the stampede, but the ostler said, in a suspicious voice: 'Here, say the word "guv", will you?'

'What are you on about?' said the coachman.

'He doesn't half sound like that bloke,' said the ostler. 'And he's out of breath!'

'Are you stupid?' said the coachman. 'He's the Postmaster! He's got a bloody key! He's got all the keys! Why the hell would he want to break into his own Post Office?'
