Miss Amity Doncaster, world traveler, is accustomed to adventure and risk. Benedict Stanbridge, a man of science and a spy for the Crown, has faced danger in the darker corners of foreign lands.             But they are about to face a threat that is shockingly close to home . . .   One does not expect to be kidnapped on a London street in broad daylight. But Amity Doncaster barely escapes with her life after she is trapped in a carriage with a blade-wielding man in a black silk mask who whispers the most vile taunts and threats into her ear. Her quick thinking, and her secret weapon, save her . . . for now.             But the monster known in the press as the Bridegroom, who has left a trail of female victims in his wake, has survived the wounds she inflicts and will soon be on his feet again.
