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 was left to work its poison. Silver, of course, clamored for his blackmail, but Miss Greeby promised to recompense him, and also threatened if he did not hold his tongue that she would accuse him and Garvington of the murder. Since the latter had forged the letter and the former had borrowed the revolver which had killed Pine, it would have been tolerably easy for Miss Greeby to substantiate her accusation. As to her share in the crime, all she had to do was to deny that Silver had passed the borrowed revolver on to her, and there was no way in which he could prove that he had done so. On the whole, Silver had judged it best to fall in with Miss Greeby's plans, and preserve silence, especially as she was rich and could supply him with whatever money he chose to ask for. She was in his power, and he was in her power, so it was necessary to act on the golden rule of give and take.
And the final statement which Silver made to Lambert intimated that Garvington was ignorant of the truth. Until the bullet was produced in the library to fit the revolver it had never struck Garvington that the other weapon had been used to kill Pine. And he had honestly believed that Silver--as was actually the case--had remained in his bedroom all the time, until he came downstairs to play his part. As to Miss Greeby being concerned in the matter, such an idea had never entered Garvington's head. The little man's hesitation in producing the revolver, when he got an inkling of the truth, was due to his dread that if Silver was accused of the murder--and at the time it seemed as though the secretary was guilty--he might turn king's evidence to save his neck, and explain the very shady plot in which Garvington had been engaged. But Lambert had forced his cousin's hand, and Silver had been brought to book, with the result that the young man now sat in his room at the inn, quite convinced that Miss Greeby was guilty, yet wondering what motive had led her to act in such a murderous way.
