"No, sir, but that helps prove. The note paper in the two houses is teetumteetotally different! That was planned to be different! Mrs. Schuyler's is a pale gray, plain paper. Miss Van Allen's is light pink, to match her boodore, I s'pose. An' it has that sort of indented frame round it, that's extry fashionable, an' a wiggly gold monogram, oh--quite a big one!" I well remembered Vicky's stationery, and the boy described it exactly. "Proves nothing!" I said, contemptuously, but I listened further. "All right," Fibsy said, wearily pushing back his shock of red hair. "Well, then, how's this? On Mrs. Schuyler's desk the pen wiper is a fancy little contraption, but it's clean-I mean it's never had a pen wiped on it. Miss Van Allen's desk hasn't got any pen wiper. On each desk is a pencil sharpener, of the same sort. On each desk is a little pincushion, with the same size of tiny pins, like she was in the habit of pinnin' bills together or sumpum like that. On each desk the blotter is in the same place and is used the same way. There's a lot of pussonality 'bout the way folks use a blotter. Some uses both sides, some only one side. Some has their blotters all torn an' sorta nibbled round the edges, an' some has 'em neat and trim. Well, the blotters on these two desks is jest alike--" "But, Fibsy," I cried in triumph, "I've seen the handwriting of these two ladies, over and over again, and they're not a bit alike!" "I know it," and Fibsy nodded. "But, Mr. Calhoun, did you know that Miss Van Allen always writes with her left hand?" "No, and I don't believe she does!" "Yessir. I went to the bank an' they said so. An' I asked the sewin' woman, an' she said so. An' I asked the caterer people an' they said so. And the inkstand is on the left-hand side of Miss Van Allen's desk." "All right, then she is left-handed, but that proves nothing!" "No, sir, Miss Van Allen ain't left-handed. You know she ain't yourself. You'd 'a' noticed it if she had been. But she writes left-handed, 'cause if she didn't she'd write like Mrs. Schuyler!" "Oh, rubbish!" I began, but Fleming Stone interrupted. "Wait, Calhoun, don't fly to pieces. All Terence is saying is quite true. I vouch for it. Listen further." "They ain't no use goin' further," said Fibsy, despondently. "Mr. Calhoun knows I'm right, only he can't bring himself to believe it, an' I don't blame him. Why, even now, he's sizin' up the case an' everything he thinks of proves it an' nothin' disproves it. But anyway, the prints prove it all." "Prints?" I said, half dazedly. "Yessir. I photographed a lot o' finger prints in both houses, an' the Headquarters people fixed 'em up for me, magnerfied 'em, you know, an' printed 'em on little cards, an' as you can see, they're all the same." I glanced at the sheaf of cards the boy had and Fleming Stone took them to scrutinize.
