When Duncan, a ship's captain, discovers he's fallen in love with the maid, he plans to tell her his feelings and make her his wife. But when some things come up missing from the Newcomb house, Brigit becomes the chief suspect. Will Duncan obey his sister's orders to rid the household of Brigit's presence? Or will the captain's heart determine his next course?
