When I entered that quiet thoroughfare it seemed deserted. Sir Walter's house was in the narrow part,and outside it three or four motor-cars were drawn up.I slackened speed some yards off and walked briskly up to the door. If the butler refused me admission, or if he even delayed to open the door, I was done.
He didn't delay. I had scarcely rung before the door opened.
'I must see Sir Walter,' I panted. 'My business is desperately important.'
That butler was a great man. Without moving a muscle he held the door open, and then shut it behind me. 'Sir Walter is engaged, Sir, and I have orders to admit no one. Perhaps you will wait.'
