"I got those prints from all sorts of places," Fibsy went on. "Off of the glass bottles and things in the bathrooms and off of the hair brushes and such things, an' off of the envelopes of letters, an' off the chairbacks an' any polished wood surfaces, an' I got lots of 'em in both houses, an' the police people picked out the best an' cleanest an' fixed 'em up, an' there you are!" They seemed to think this settled the matter. But I would not be convinced. Of course, I'd been told dozens of times that no two people in the world have finger prints alike, but that didn't mean a thing to me. It might be, I told them, that Vicky Van and Ruth Schuyler were friends, that Ruth had withheld this fact, and that-- "No," said Stone, "not friends, but identical--the same woman. And, listen to this. Mrs. Schuyler heard us say this evening that Fibsy could photograph the brushes and such things over here to get Miss Van Allen's finger prints, and what does she do? She sends Tibbetts over to scrub and wipe off those same brushes, also the mirrors, chairbacks and all such possible evidence. A hopeless task--for the woman couldn't eradicate all the prints in the house. And, also, it was too late, for Fibsy had already done his camera work." "How do you know she did all that?" and I glowered at the detective. "Because Fibsy just told me he found evidences of this cleaning up, and, too, because Mrs. Schuyler purposely kept us over there longer than we intended to stay. You know how, when we proposed to say good-night, she urged us to stay longer. That was to give her maid more time for the work. Now, Mr. Calhoun, go on with your objections to our conclusions. It helps our theory to answer your refutations." "Her letters," I mumbled, scarce able to formulate my teeming thoughts. "Vicky Van sent a letter to Ruth Schuyler--" "Of course, she did. Wrote it herself, with her left hand, and mailed it to her other personality, in order to make the police give up the search. And, too, the letter from Miss Van Allen, found in Randolph Schuyler's desk after his death, was written and placed there by Mrs. Schuyler for us to find." "Impossible!" I cried. "I won't allow these libels. You'll be saying next that Ruth Schuyler killed her husband!" "She did," asserted Fleming Stone, gravely. "She did kill him, in her character as Vicky Van. Don't you see it all? Schuyler came here as Somers, never dreaming that Vicky Van was his own wife in disguise. Or, he may have suspected it, and may have come to verify his suspicion. Any way, when she saw and recognized him, whether he knew her or not, she lured him out to the dining room and stabbed him with the caterer's knife."
