The girls had withdrawn long before this, just as Mr. Gryce had desired, and I now expected to be allowed to join them, but Mr. Gryce detained me till the grave was refilled and made decent again, when he turned and to my intense astonishment--for I had thought the matter was all over and the exoneration of this household complete--said softly and with telling emphasis in my ear: "Our work is not done yet. They who make graves so readily in cellars must have been more or less accustomed to the work. We have still some digging to do." XXXI STRATEGY I was overwhelmed. "What," said I, "you still doubt?" "I always doubt," he gravely replied. "This cellar bottom offers a wide field for speculation. Too wide, perhaps, but, then, I have a plan." Here he leaned over and whispered a few concise sentences into my ear in a tone so low I should feel that I was betraying his confidence in repeating them. But their import will soon become apparent from what presently occurred. "Light Miss Butterworth to the stairway," Mr. Gryce now commanded one of the men, and thus accompanied I found my way back to the kitchen, where Hannah was bemoaning uncomforted the shame which had come upon the house. I did not stop to soothe her. That was not my cue, nor would it have answered my purpose. On the contrary, I broke into angry ejaculations as I passed her: "What a shame! Those wretches cannot be got away from the cellar. What do you suppose they expect to find there? I left them poking hither and thither in a way that will be very irritating to Miss Knollys when she finds it out. I wonder William stands it." What she said in reply I do not know. I was half way down the hall before my own words were finished. My next move was to go to my room and take from my trunk a tiny hammer and some very small, sharp-pointed tacks. Curious articles, you will think, for a woman to carry on her travels, but I am a woman of experience, and have known only too often what it was to want these petty conveniences and not be able to get them. They were to serve me an odd turn now. Taking a half-dozen tacks in one hand and concealing the hammer in my bag, I started boldly for William's room. I knew that the girls were not there, for I had heard them talking together in the sitting-room as I came up. Besides, if they were, I had a ready answer for any demand they might make. Searching out his boots, I turned them over, and into the sole of each I drove one of my small tacks. Then I put them back in the same place and position in which I found them. Task number one was accomplished. When I issued from the room, I went as quickly as I could below. I was now ready for a talk with the girls, whom I found as I had anticipated, talking and weeping together in the sitting-room. They rose as I came in, awaiting my first words in evident anxiety. They had not heard me go up-stairs. I immediately allowed my anxiety and profound interest in this matter to have full play.
