'He may be a School-prefect, Mr Perceval, but the fact remains that he is a trespasser, and ought from your point of view to be punished for breaking bounds.'

The Head suddenly looked almost cheerful again.

'Of course,' he said, 'of course. I thought that there must be an explanation. The rules respecting bounds, Sir Alfred, do not apply to School-prefects, only to the rest of the School.'

'Indeed?' said Sir Alfred. His tone should have warned the Head that something more was coming, but it did not. He continued.

'Of course it was very wrong of him to trespass on your land, but I have no doubt that he did it quite unintentionally. I will speak to him, and I think I can guarantee that he will not do it again.'

'Oh,' said his visitor. 'That is very gratifying, I am sure. Might I ask, Mr Perceval, if School-prefects at St Austin's have any other privileges?'

The Head began to look puzzled. There was something in his visitor's manner which suggested unpleasant possibilities.

'A few,' he replied. 'They have a few technical privileges, which it would be a matter of some little time to explain.'

'It must be very pleasant to be a prefect at St Austin's,' said Sir Alfred nastily. 'Very pleasant indeed. Might I ask, Mr Perceval, if the technical privileges to which you refer include—smoking?'

The Head started as if, supposing such a thing possible, someone had pinched him. He did not know what to make of the question. From the expression on his face his visitor did not appear to be perpetrating a joke.
