the hour of eleven
Have you a swift horse that knows the way from Potsdam to Berlin , and can find it by night ? '' `` I have a swift horse , and for me and my horse there is no night . '' `` Four nights from this you will find the window which you know open , and the door which leads to the small stair , only closed . Come at the hour of eleven , and you will receive a compensation for the scarf you have lost this evening . Hush -- no word ; look not around , move onward indifferently ; turn not your head . Farewell ! in four days -- at eleven -- go ! ''
