However, it appeared that she was duly informed of the hour when Pine would probably arrive to prevent the pretended elopement, and also learned that he would be hanging about the blue door.  When Silver retired for the night he watched the door of her bedroom—­which was in the same wing of the mansion of his own.  Also he occasionally looked out to see if Pine had arrived, as the window of his room afforded a fair view of the blue door and the shrubbery.  For over an hour—­as he told Lambert—­he divided his attention between the passage and the window.  It was while looking out of the last, and after midnight, that he saw Miss Greeby climb out of her room and descend to the ground by means of the ivy which formed a natural ladder.  Her window was no great height from the ground, and she was an athletic woman much given to exercise.  Wondering what she intended to do, yet afraid—­because of Pine’s expected arrival—­to leave the house, Silver watched her cautiously.  She was arrayed in a long black cloak with a hood, he said, but in the brilliant moonlight he could easily distinguish her gigantic form as she slipped into the shrubbery.  When Pine arrived, Silver saw him dash at the blue door when it was opened by Garvington, and saw him fall back after the first shot.  Then he heard the shutting of the door; immediately afterward the opening of Lady Agnes’s window, and noted that Pine ran quickly and unsteadily down the path.  As he passed the shrubbery, the second shot came—­at this point Silver simply gave the same description as Lady Agnes did at the inquest—­and then Pine fell.  Afterward Garvington and his guests came out and gathered round the body, but Miss Greeby, slipping along the rear of the shrubbery, doubled back to the shadow at the corner of the house.  Silver, having to play his part, did not wait to see her re-enter the mansion, but presumed she did so by clambering up the ivy.  He ran down and mingled with the guests and servants, who were clustered round the dead man, and finally found Miss Greeby at his elbow, artlessly inquiring what had happened.  For the time being he accepted her innocent attitude.

Later on, when dismissed by Jarwin and in want of funds, he sought out Miss Greeby and accused her.  At first she denied the story, but finally, as she judged that he could bring home the crime to her, she compromised with him by giving him the post of her secretary at a good salary.  When he obtained the forged letter from Chaldea—­and she learned this from Lambert when he was ill—­Miss Greeby made him give it to her, alleging that by showing it to Agnes she could the more positively part the widow from her lover.  Miss Greeby, knowing who had written the letter, counted upon Agnes guessing the truth, and had she not seen that it had entered her mind, when the letter was brought to her, she would have given a hint as to the forger’s name.  But Agnes’s hesitation and sudden paleness assured Miss Greeby that she guessed the truth, so the letter
