Con Somerford, Viscount Amleigh, is not pleased to have inherited the Earldom of Wyvern and the monstrous house that goes with it. He's even less pleased when the first person he encounters there is Susan Kerslake with a pistol in her hands
Susan and he have a past, a bitter one. The years in between, however, have been years of war. That must, surely, have armed him so he can resist her, and deal with the smuggling with which she is clearly involved.
