'No, sir. I can prove what I say. If I had not gone to London with him that last time, he'd have got away with the boy then, for certain.'

For an instant an uneasy thought came to me that he might have something in reserve, something unknown to me, which had encouraged him to this direct attack. I dismissed the notion. There could be nothing.

Mr Abney had turned to me with a look of hopeless bewilderment. I raised my eyebrows.

'Ridiculous,' I said.

That this was the only comment seemed to be Mr Abney's view. He turned on Sam with the pettish anger of the mild man.

'What do you mean, White, by coming to me with such a preposterous story?'

'I don't say Mr Burns wished to kidnap the boy in the ordinary way,' said Sam imperturbably, 'like those men who came that night. He had a special reason. Mr and Mrs Ford, as of course you know, sir, are divorced. Mr Burns was trying to get the boy away and take him back to his mother.'

I heard Audrey give a little gasp. Mr Abney's anger became modified by a touch of doubt. I could see that these words, by lifting the accusation from the wholly absurd to the somewhat plausible, had impressed him. Once again I was gripped by the uneasy feeling that Sam had an unsuspected card to play. This might be bluff, but it had a sinister ring.

'You might say,' went on Sam smoothly, 'that this was creditable to Mr Burns's heart. But, from my employer's viewpoint and yours, too, it was a chivalrous impulse that needed to be checked. Will you please read this, sir?'

He handed a letter to Mr Abney, who adjusted his glasses and began to read—at first in a detached, judicial way, then with startled eagerness.
