He bent forward and tapped me on the knee.

'I propose to stick to you like a label on a bottle, sonny,' he said. 'That's what I propose to do.'

'What do you mean?'

I was finding it difficult, such is the effect of a guilty conscience, to meet his eye, and the fact irritated me.

'I want to find out that address you gave the Ford kid this morning out in the stable-yard.'

It is strange how really literal figurative expressions are. I had read stories in which some astonished character's heart leaped into his mouth. For an instant I could have supposed that mine had actually done so. The illusion of some solid object blocking up my throat was extraordinarily vivid, and there certainly seemed to be a vacuum in the spot where my heart should have been. Not for a substantial reward could I have uttered a word at that moment. I could not even breathe. The horrible unexpectedness of the blow had paralysed me.

White, however, was apparently prepared to continue the chat without my assistance.

'I guess you didn't know I was around, or you wouldn't have talked that way. Well, I was, and I heard every word you said. Here was the money, you said, and he was to take it and break for London, and go to the address on this card, and your pal Smith would look after him. I guess there had been some talk before that, but I didn't arrive in time to hear it. But I heard all I wanted, except that address. And that's what I'm going to find out when we get to London.'

He gave out this appalling information in a rich and soothing voice, as if it were some ordinary commonplace. To me it seemed to end everything. I imagined I was already as good as under arrest. What a fool I had been to discuss such a matter in a place like a stable yard, however apparently empty. I might have known that at a school there are no empty places.

'I must say it jarred me when I heard you pulling that stuff,' continued White. 'I haven't what you might call a childlike faith in my fellow-man as a rule, but it had never occurred to me for a moment that you could be playing that game. It only shows,' he added philosophically, 'that you've got to suspect everybody when it comes to a gilt-edged proposition like the Little Nugget.'
