“Why, that of a jealous woman. Miss Van Norman was just about to marry the man Miss Dupuy is in love with. Perhaps—do have patience, I’m merely supposing—perhaps she has vainly urged Miss Van Norman to give him up, and, finding she wouldn’t do so, at the last minute she prevented the marriage herself,—putting that paper on the table to make it appear a suicide. This would explain her stealthy attempt to regain possession of the paper later.”
“Why should she want it?”
“So that it couldn’t be proved not to be in Miss Van Norman’s writing.”
“It’s ingenious on your part,” said Kitty slowly, “but it can’t be true. Cicely may be in love with Schuyler, but she wouldn’t kill Maddy because of that.”
“Who can tell what a hysterical, jealous woman will do?” said Rob, with the air of an oracle. “And moreover, to my mind, that explains her half-conscious exclamation of which you just told me. When she said, ‘They must not think Schuyler did it,’ it meant that she knew he didn’t do it, but she didn’t want suspicion to rest on him. That’s why she insists it was a suicide.”
So in earnest was Fessenden that Kitty felt almost convinced there was something in his theory.
“But it can’t be,” she said, at last, with an air of finality. “It wouldn’t be possible for Cicely to do such a thing! I know her too well!”
“Then, Miss French, if that, to you, is a logical argument, you must admit mine. It wouldn’t be possible for Carleton to do such a thing! I know him too well!”
Kitty had to smile at the imitation of the strong inflections she had used, and, too, she had to admit that one opinion was as permissible as the other.
“You see,” went on Rob quietly, “we’re not really assuming Miss Dupuy’s guilt, we’re only seeing where these deductions lead us. Suppose, for the moment, that Miss Dupuy did, during that half-hour in the library, have an altercation with Miss Van Norman, and just suppose,—or imagine, if you prefer the word,—that she turned the dagger upon her friend and employer, wouldn’t her subsequent acts have been just as they were? At Mr. Carleton’s alarm, she came downstairs, fully dressed; later she tried to remove secretly that written paper; always at serious questioning she faints or flies into hysterics; and, naturally, when suspicion comes near the man she cares for, she tries to turn it off. And then, too, Miss French, a very strong point against her is that she was the last one, so far as we know, to see Miss Van Norman alive. Of course, the murderer was the last one; but I mean, of the witnesses, Miss Dupuy was the latest known to be with Miss Van Norman. Thus, her evidence cannot be corroborated, and it may or may not be true. If she is the guilty one, we cannot expect the truth from her, and so we must at least admit that there is room for investigation, if not suspicion.”
