two o'clock
snapped Harley -- `` neither will Scotland Yard overlook it . '' He was in a particularly impossible mood , for he so rarely made mistakes that to be detected in one invariably brought out those petulant traits of character which may have been due in some measure to long residence in the East . Recognizing that he would rather be alone I parted from him at the corner of Chancery Lane and returned to my own chambers . Furthermore , I was very tired , for it was close upon two o'clock , and on turning in I very promptly went to sleep , nor did I awaken until late in the morning . For some odd reason , but possibly because the fact had occurred to me just as I was retiring , I remembered at the moment of waking that I had not told Harley about the romantic wedding of Captain Dan . As I had left my friend in very ill humour I thought that this would be a good excuse for an early call , and just before eleven o'clock I walked into his office . Innes , his invaluable secretary , showed me into the study at the back .
