Two o'clock
I looked at sympathetic little Mrs. Brown ; and the thought of Watson 's pups covered me with guilty confusion . Mrs. Brown had agreed to sit up with me until he arrived . One o'clock came , but no Baby . Two o'clock , three o'clock , passed . It was almost four when there was a wild clatter of horses ' hoofs outside , and with a jerk a wagon stopped at the door . In an instant I had opened it , and confronted a stranger . Almost at the same moment , the horses attempted to run away with the wagon .
