eight o'clock
I knelt down by the window , put my elbows on the sill , and resolved to wait there awhile , to see if the nocturnal disturber would hike out again . Apparently I fell asleep in this attitude , for the next thing I knew , Holmes , fully dressed , was bending over me with a grin on his face , and it was broad daylight . `` Well , why do n't you wake up yourself , Doc ? It 's eight o'clock , '' he said . Then I arose sheepishly , and dressed . After our ablutions in the lavatory next door , -- where we helped ourselves to a bottle of whiskey we found in a medicine cabinet on the wall , -- we descended the two flights of stairs to the main floor . Finding nobody around , we walked through the different rooms on an exploring tour , seeking evidences of the disturbance the night before .
