on this certain fine sunday, mr. lorry walked towards soho, early in the afternoon, for three reasons of habit. firstly, because, on fine sundays, he often walked out, before dinner, with the doctor and lucie; secondly, because, on unfavourable sundays, he was accustomed to be with them as the family friend, talking, reading, looking out of window, and generally getting through the day; thirdly, because he happened to have his own little shrewd doubts to solve, and knew how the ways of the doctor's household pointed to that time as a likely time for solving them.
