Besides, he had another weapon with which to rouse his father's anger against the Dalmatian.

Since Marietta had defied him and had gone to see Zorzi in the laboratory, he had not found what he considered a convenient opportunity of speaking to her on the subject; that is to say, he had lacked the moral courage to do so at all.

But it would need no courage to complain of her conduct to their father, and though Beroviero's anger might fall chiefly upon Marietta, a portion of it would take effect against Zorzi.
