Basil Grant took out his watch with an abrupt movement . `` When did you say the British Museum man was coming ? '' he said . `` Three o'clock , '' said Miss Chadd briefly . `` Then I have an hour before me , '' said Grant , and without another word threw up the window and jumped out into the garden . He did not walk straight up to the doctor and lunatic , but strolling round the garden path drew near them cautiously and yet apparently carelessly . He stood a couple of feet off them , seemingly counting halfpence out of his trousers pocket , but , as I could see , looking up steadily under the broad brim of his hat .
