five o'clock
Luigi did n't wait to be told a second time , but went up the stairs with considerable alacrity , while Holmes and I followed close behind . When we reached the fifth and top floor , we entered Luigi 's room there , and the latter changed clothes with Holmes . As they were both of the same height and build , and were both of dark complexion , the second gardener would not recognize my partner that evening until he got up close to him , so Holmes was playing it rather safe . `` I think I 'll just keep these valet 's togs on , for the fun of it , and then I 'll be all ready when five o'clock comes , '' said Holmes after we had locked Luigi in his room and were descending the stairs . `` Gee , but I wish they 'd put in an elevator in this darned old-fashioned castle ! My legs are getting kind of tired running up and down five flights of stairs . '' As we reëntered the library , where the Earl , Tooter , and Thorneycroft looked up with surprise as they saw Holmes come back in Vermicelli 's clothes , Lord Launcelot and Billie Hicks came in .
