'Well, if that's the case, let there be no secrets between us.
He's asleep in the next room.'
Sam leaned forward earnestly and tapped me on the knee.
'Young man, this is a critical moment. This is where, if you aren't careful, you may undo all the good work you have done by getting chesty and thinking that, because you've won out so far, you're the whole show. Believe me, the difficult part is to come, and it's right here that you need an experienced man to work in with you. Let me in on this and leave the negotiations with old man Ford to me. You would only make a mess of them. I've handled this kind of thing a dozen times, and I know just how to act. You won't regret taking me on as a partner. You won't lose a cent by it. I can work him for just double what you would get, even supposing you didn't make a mess of the deal and get nothing.'
'It's very good of you, but there won't be any negotiations with Mr Ford. I am taking the boy back to Sanstead, as I told you.' I caught his pained eye. 'I'm afraid you don't believe me.'
He drew at his cigar without replying.
It is a human weakness to wish to convince those who doubt us, even if their opinion is not intrinsically valuable. I remembered that I had Cynthia's letter in my pocket. I produced it as exhibit A in my evidence and read it to him.
Sam listened carefully.
'I see,' he said. 'Who wrote that?'
'Never mind. A friend of mine.'
I returned the letter to my pocket.
