ten o’clock before
This was carefully done , and an elaborate arrangement of string was made , leading out from the statue to the place where the Lord-Lieutenant was to stand . Dr. O'Grady satisfied himself by a series of experiments that the apparatus would work . At a single pull at the end of the string the whole sheet fluttered to the ground and exposed the Deputy-Lieutenant to public view . It was ten o'clock before these arrangements were completed and the step-ladders taken away . Dr. O'Grady went into the barrack and warned Sergeant Colgan that he would be held personally responsible if any curious wayfarer pulled the string before the proper time . Sergeant Colgan at once ordered Moriarty to mount guard over the statue . Dr. O'Grady went over to the hotel and inspected the luncheon table .
