two in the morning
There was the address -- a house in Grosvenor Street . Overcome by an uncontrollable impulse , he went out of the room . Going to his own he found his mackintosh and a round hat , and softly left the house . It was then past two in the morning , pouring with rain , and blowing hard . He had been a little in London as a lad and remembered the main thoroughfares , so had no great difficulty in finding his way up Piccadilly till he came to Park Lane , into which the Red book told him Grosvenor Square opened . But to find Grosvenor Street itself was a more difficult matter , and at such a time on such a night there was naturally nobody to ask -- least of all a policeman . At last he found it , and hurried on down the street with a quickening pulse .
