To this was pinned a line in a delicate aristocratic hand, saying that the Archbishop would willingly listen to Madam San Croix's statement if she would come to him on Friday morning at eleven.

"You see," said Walcott, desperately, "there is no possible way out. I know the woman—when she decides to do a thing that is the end of it. She has decided to do this."

Mason turned around from the table, stretched out his long legs, and thrust his hands deep into his pockets. Walcott sat with his head down, watching Mason hopelessly, almost indifferently, his face blank and sunken. The ticking of the bronze clock on the mantel-shelf was loud, painfully loud. Suddenly Mason drew his knees in and bent over, put both his bony hands on the table, and looked at Walcott.

"Sir," he said, "this matter is in such shape that there is only one thing to do. This growth must be cut out at the roots, and cut out quickly. This is the first fact to be determined, and a fool would know it. The second fact is that you must do it yourself. Hired killers are like the grave and the daughters of the horse-leech,—they cry always, 'Give, Give,' They are only palliatives, not cures. By using them you swap perils. You simply take a stay of execution at best. The common criminal would know this. These are the facts of your problem. The master plotters of crime would see here but two difficulties to meet:

"A practical method for accomplishing the body of the crime.

"A cover for the criminal agent.

"They would see no farther, and attempt to guard no farther. After they had provided a plan for the killing, and a means by which the killer could cover his trail and escape from the theatre of the homicide, they would believe all the requirements of the problems met, and would stop. The greatest, the very giants among them, have stopped here and have been in great error.

"In every crime, especially in the great ones, there exists a third element, pre-eminently vital. This third element the master plotters have either overlooked or else have not had the genius to construct. They plan with rare cunning to baffle the victim. They plan with vast wisdom, almost genius, to baffle the trailer. But they fail utterly to provide any plan for baffling the punisher. Ergo, their plots are fatally defective and often result in ruin. Hence the vital necessity for providing the third element—the escape ipso jure."

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.
