227. The Round Table Affair 3/25/1966
Lucho Nostra and a group of criminals take over a tiny European country, Ingolstein, because it has no extradition treaty. Prince Frederick is afraid to kick them out, so Solo convinces princess Vicky to return and do so, only to find that she cannot because the treasury has been replaced with IOU's to Nostra for the prince's gambling debts. Nostra arranges for permanent protection by forcing a marriage between Vicky and one of his henchmen, Artie King, but the two actually do fall in love. King duels Nostra, with the fate of the country riding on the outcome.
