“After we make absolutely sure that you are dead we throw a lot of soft mortar into the grave, deposit the corpse, and then pour in more cement--so that you will be completely surrounded by it. It will make it very difficult indeed to recognize you when they try to chip away the hard cement--if they ever try! Then we fill the grave up to the top with concrete, using plenty of steel rods--not to re-enforce the concrete at all, but to make it very hard digging with a pick. “We also stick the soilpipe into the--er--cavity in order to account for the disturbed pavement. Intelligent searchers--your son and his detectives--will assume it is plumbing--and seek no further. We replace the plank flooring in the bin and fill it up with coal, thereby further obliterating all traces of your grave. “We have provided for that part, you see. Why, my dear Mr. Merriwether, what we really do to you is confer immortality on you. We elevate you to the rank of one of the mysteries. Charlie Ross and E. H. Merriwether! Just assume that we'll do what I say. Very well! Now, visualize the search made for you. Endow your people with superhuman ingenuity. Useless!” The man waved a hand toward Mr. Merriwether; but Mr. Merriwether said: “You assume that the search will be exclusively for me--but they will also search for you!” “My dear sir, that is unkind of you!” The man spoke reproachfully. “We know that when we go into the plunder-recovery business we must guard against the chief contributory cause of the vast majority of all business' failures, according to the statistics of Dun and Bradstreet--to wit, insufficient capital. Murderers are caught when their faces and habits and families are known. Usually their lack of means forces them to betray themselves. But nobody knows how the men who will kill E. H. Merriwether look, simply because we have enough money to go anywhere. We will become tourists--like thousands of others. Some of us will stay in New York; others will go on round-the-world tours. See this?” The man pulled from his pocket some packages of well-worn bills, with the bank-wrappers round them, though a finger hid the bank name. Also the man showed to Mr. Merriwether several books of travelers' checks of the fifty-dollar denomination--the specimen signature also being covered by the man's finger.
