9:45
So when Keith had completed his arrangements , he found Dennison at supper at a table near the ladies ' entrance , a view of which he commanded in a mirror just before him . Mr. Dimm 's manner had entirely changed . He was a man of the world and a host as he handed Keith to his seat . `` A supper for two has been ordered in private dining-room 21 , for 9:45 , '' he said in an undertone as the waiter moved off . `` They do not know whether it is for a gentleman and a lady , or two gentlemen ; but I suppose it is for a lady , as he has been here a number of times with ladies . If you are sure that the lady will not come , you might wait for him there . I will remain here until he comes , and follow him up , in case you need me . ''
