‘We had to do our duty,’ they said. ‘Took the young gentlemen into custody for their own protection.’

Mulcaster looked crapulous and began a confused complaint that he had been denied legal representation and civil rights. Rex said: ‘Better leave all the talking to me.’

I was clear-headed now and watched and listened with fascination while Rex settled our business. He examined the charge sheets, spoke affably to the men who had made the arrest; with the slightest perceptible nuance he opened the way for bribery and quickly covered it when he saw that things had now lasted too long and the knowledge had been too widely shared; he undertook to deliver us at the magistrate’s court at ten next morning, and then led us away. His car was outside.

‘It’s no use discussing things tonight. Where are you sleeping?’

‘Marchers,’ said Sebastian.

‘You’d better come to me. I can fix you up for tonight. Leave everything to me.’

It was plain that he rejoiced in his efficiency.

Next morning the display was even more impressive. I awoke with the startled and puzzled sense of being in a strange room, and in the first seconds of consciousness the memory of the evening before returned, first as though of a nightmare, then of reality. Rex’s valet was unpacking a suitcase. On seeing me move he went to the wash-hand stand and poured something from a bottle. ‘I think I have everything from Marchmain House,’ he said. ‘Mr Mottram sent round to Heppell’s for this.’

I took the draught and felt better.

A man was there from Trumper’s to shave us.

Rex joined us at breakfast. ‘It’s important to make a good appearance at the court,’ he said. ‘Luckily none of you look much the worse for wear.’

After breakfast the barrister arrived and Rex delivered a summary of the case.

‘Sebastian’s in a jam,’ he said. ‘He’s liable to anything up to six months’ imprisonment for being drunk in charge of a car. You’ll come up before Grigg unfortunately. He takes rather a grim view of cases of this sort. All that will happen this morning is that we shall ask to have Sebastian held over for a week to prepare the defence. You two will plead guilty, say you’re sorry, and pay your five bob fine. I’ll see what can be done about squaring the evening papers. The Star may be difficult.

‘Remember, the important thing is to keep out all mention of the Old Hundredth. Luckily the tarts were sober and aren’t being charged, but their names have been taken as witnesses. If we try and break down the police evidence, they’ll be called. We’ve got to avoid that at all costs, so we shall have to swallow the police story whole and appeal to the magistrate’s good nature not to wreck a young man’s career for a single boyish indiscretion. It’ll work all right. We shall need a don to give evidence of good character. Julia tells me you have a tame one called Samgrass. He’ll do. Meanwhile your story is simply that you came up from Oxford for a perfectly respectable dance, weren’t used to wine, had too much, and lost the way driving home.
