five o'clock
`` I thought you were only humbugging ; really I did . '' `` I 've a good mind to do what you think . You 'd better mind your eye , I can tell you -- I wish Wally would come . There 's five o'clock striking -- I 'll go and look for him . Ashby , you see if he 's in the library ; you kids , stay here , and lock the door , and do n't let anybody in but Wally . Do you hear ? If you do , you 'll get it pretty hot for being out of your house .
