"Thwart the whole darned thing," Sinclair exclaimed emphatically.
"But can't she thwart it without her domino?"
"I should think not! You see, if it hadn't been for the domino, the Dog would have spotted her quick as a wink. Only when he sees her in the domino with this rose in her hair, he thinks she must be Lucia dell' Esterolla."
"Say, he fools himself, doesn't he? Who's this last girl?"
"Lucia? Oh, she's great!" Sinclair said. "She's one of those Southern natures, you know, full of—er—full of . . . "
"Full of fun," I suggested.
"Oh, hang it all, don't make fun of it! Well, anyhow, she's sister, you understand, to the Contessa Carantarata, and that's why Fra Fraliccolo, or . . . hold on, that's not it, no, no, she's not sister to anybody. She's cousin, that's it; or, anyway, she thinks she is cousin to Fra Fraliccolo himself, and that's why Pio tries to stab Fra Fraliccolo."
"Oh, yes," I assented, "naturally he would."
