'Has anything been heard about Thomson, sir?' said Tony, as he entered.

'That is just what I want to see you about. Graham, will you go and bring the rest of the prefects here?'

'Now,' he said, as Tony returned with Swift and Daintree, the two remaining House-prefects, 'you all know, of course, that Thomson is not in the House. The Headmaster wants you to go and look for him. Welch seems to have been the last to see him, and he left him lying in a ploughed field near Parker's Spinney. You all know Parker's Spinney, I suppose?'

'Yes, sir.'

'Then you had better begin searching from there. Go in twos if you like, or singly. Don't all go together. I want you all to be back by eleven. All got watches?'

'Yes, sir.'

'Good. You'd better take lanterns of some sort. I think I can raise a bicycle lamp each, and there is a good moon. Look everywhere, and shout as much as you like. I think he must have sprained an ankle or something. He is probably lying somewhere unable to move, and too far away from the road to make his voice heard to anyone. If you start now, you will have just an hour and a half. You should have found him by then. The prefects from the other Houses will help you.'

Daintree put in a pertinent question.

'How about trespassing, sir?'

'Oh, go where you like. In reason, you know. Don't go getting the School mixed up in any unpleasantness, of course, but remember that your main object is to find Thomson. You all understand?'
