'Sir to you,' said Charteris. 'Look here, Babe, we want to know what you have done with Jim. He was seen by competent witnesses to go off with you, and he's not come back. If you've murdered him, you might let us have the body.'

'Not come back! Rot. Are you certain?'

'My dear chap, every House-prefect on the list has been sent out to look for him. When did he leave here?'

The Babe reflected.

'Six, I should think. Little after, perhaps. Why—oh Lord!'

He broke off suddenly.

'What's up?' asked Tony.

'Why I sent him by a short cut through some woods close by here, and I've only just remembered there's a sort of quarry in the middle of them. I'll bet he's in there.'

'Great Scott, man, what sort of a quarry? I like the calm way the Babe talks of sending unsuspecting friends into quarries. Deep?'

'Not very, thank goodness. Still, if he fell down he might not be able to get up again, especially if he'd hurt himself at all. Half a second. Let me get on some boots, and I'll come out and look. Shan't be long.
