'We must take the risk. Our only chance is to make a bold dash for it, and we can't leave the wounded here.'

'I suppose there's going to be a deuce of a row,' said Walker.

'At this moment I'm going to fill my pipe.'

'I gather from the general amiability of your demeanour that we're in rather a tight place.'

'Tighter than any of your patent-leather boots, my friend.'

Walker moved uncomfortably in his chair. He no longer felt sleepy. A cold shiver ran down his spine.

'Have we any chance of getting through?' he asked gravely.
