"It ain't only this thing or that thing, Mr. Calhoun," said Fibsy, earnestly. "It's the pilin' up of all 'em. An' I ain't through yet. Here's another point. Miss Van Allen, she ain't got any pitchers of nature views—no landscapes nor woodsy dells in this whole house. She jest likes pitchers of people—pretty girls, an' old cavalier gentlemen, an nymps, an' kiddy babies—but all human, you know. Now, Mrs. Schuyler, she don't care anythin' special for nature, neither. I piped up about the beauty scenery out Westchester way an' over in the park, an' it left her cold an' onintrusted. But she has portfolios of world masterpieces, or whatever you call 'em, over to that house, an' they're all figger pieces."

"And her writing desk," prompted Stone.

"Yessir, that checked up, too. You know, Mr. Calhoun, they ain't nothin' more intim'tly pers'nal than a writin' desk. Well, Miss Van Allen's has a certain make of pen, an' a certain number and kind of pencils. An' Mrs. Schuyler, she uses the same identical styles an' numbers."

"And notepaper, I suppose," I flung back, sarcastically.

"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?"
