If all else fails, I recommend that Sharina do to this idiot prince what General Alois Eliáš (the unwilling puppet ruler of the Czech Republic during the Nazi occupation) did to some Czech Nazi collaborators during WW2: lace a sandwich with lethal bacteria and let the bugs do their work. The General was investigated by the Gestapo but got away scot-free; this idiot's guards are at best half as competent or ruthless as the Gestapo.
