Two o'clock
The Doctor had a sheaf of letters from her . And so the morning 's task was over . He turned a page and came to the afternoon . `` Two o'clock , Mrs. Lesueur ; two-thirty , Miss Mendish ; three , the Dean of Greystone ; three-thirty , Lady Carle ; four , Madame de Lys ; four-thirty , Mrs. Harringby ; five , Sir Henry Grebe ; five-thirty , Mrs. Chepstow . '' The last name was that of the last patient . Doctor Meyer Isaacson 's day 's work was over at six , or was supposed to be over . Often , however , he gave a patient more than the fixed half-hour , and so prolonged his labours .
