ten minutes to twelve
`` I wish I had n't lost my suit-case , '' Dick observed ruefully . `` I bet anything it 's in that house in Cumberland Place where the taxi stopped -- unless the woman who met me at Paddington intentionally left it in the taxi when she found I had jumped out and run away . We ought to inquire at Scotland Yard , ought n't we ? '' We arrived at Willow Road , Hampstead , at ten minutes to twelve . Telling Dick to remain in the taxi , I got out and rang the bell . The door was opened by a maid I had not seen before , and when I inquired for Miss Challoner she stared at me blankly -- indeed , as I thought , suspiciously . `` Nobody of that name lives here , '' she said curtly .
