"Like I said."

"All right."

"Who should turn up and thwart the whole scheme, but this
Signorina Tarara in her domino..."

"Hully Gee!" I said, "you make my head ache. What the
deuce does she come in her domino for?"

"Why, to thwart it."

"To thwart what?"

"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.
