Mason arose, walked around the table, and put his hand firmly on Samuel Walcott's shoulder. "This must be done to-morrow night," he continued; "you must arrange your business matters to-morrow and announce that you are going on a yacht cruise, by order of your physician, and may not return for some weeks. You must prepare your yacht for a voyage, instruct your men to touch at a certain point on Staten Island, and wait until six o'clock day after to-morrow morning. If you do not come aboard by that time, they are to go to one of the South American ports and remain until further orders. By this means your absence for an indefinite period will be explained. You will go to Nina San Croix in the disguise which you have always used, and from her to the yacht, and by this means step out of your real status and back into it without leaving traces. I will come here to-morrow evening and furnish you with everything that you shall need and give you full and exact instructions in every particular. These details you must execute with the greatest care, as they will be vitally essential to the success of my plan." Through it all Walcott had been silent and motionless. Now he arose, and in his face there must have been some premonition of protest, for Mason stepped back and put out his hand. "Sir," he said, with brutal emphasis, "not a word. Remember that you are only the hand, and the hand does not think." Then he turned around abruptly and went out of the house. III. The place which Samuel Walcott had selected for the residence of Nina San Croix was far up in the northern suburb of New York. The place was very old. The lawn was large and ill-kept; the house, a square old-fashioned brick, was set far back from the street, and partly hidden by trees. Around it all was a rusty iron fence. The place had the air of genteel ruin, such as one finds in the Virginias. On a Thursday of November, about three o'clock in the afternoon, a little man, driving a dray, stopped in the alley at the rear of the house. As he opened the back gate an old negro woman came down the steps from the kitchen and demanded to know what he wanted. The drayman asked if the lady of the house was in. The old negro answered that she was asleep at this hour and could not be seen. "That is good," said the little man, "now there won't be any row. I brought up some cases of wine which she ordered from our house last week and which the Boss told me to deliver at once, but I forgot it until to-day. Just let me put it in the cellar now, Auntie, and don't say a word to the lady about it and she won't ever know that it was not brought up on time." The drayman stopped, fished a silver dollar out of his pocket, and gave it to the old negro. "There now, Auntie," he said, "my job depends upon the lady not knowing about this wine; keep it mum."
