ten o'clock
Only in the matter of having some of his hands to sleep at the mill Ned declined to act on the advice of his new friend . `` No , '' he said ; `` I am determined that I will have no lives risked in the defense of our property . It has cost us dearly enough already . '' But though Ned refused to have any of his hands to sleep at the mill , he had a bed fitted up in his office , and every night at ten o'clock , after Charlie had gone to bed , he walked out to the mill and slept there : Heavy shutters were erected to all the lower windows , and bells were attached to these and to the doors , which would ring at the slightest motion . A cart one evening arrived from Huddersfield after the hands had left the mill , and under Ned 's direction a number of small barrels were carried up to his office . Although three months had now elapsed since his return home he had never once seen his mother , and the knowledge that she still regarded him as the murderer of her husband greatly added to the bitterness of his life . Of an evening after Lucy had gone to bed he assisted Charlie with his lessons , and also worked for an hour with Bill Swinton , who came regularly every evening to be taught .
