Sandra of the Secret Service: "The Gavonian Affair, Part 12 (of 13)"
Sandra and her friends are arrested by Princess Yonda's soldiers. Sandra claims to be the real Princess Yonda, and when the soldiers ask for proof, she shows them the *Locket of Authority*. It's not Sandra after all! Yonda orders the soldiers to release Count de Wex's party. By this time, Count Tauru and his traitorous soldiers come running out of the tunnel exit; Yonda orders the loyal troops to arrest them! Soon Count Tauru is tossed into the dungeon, taking the place of Sandra's two American friends, who are escorted to the border and ordered never to return to Gavonia.
Meanwhile in an isolated chateau high in the hills, a villain is gloating at Sandra, (believing her to be Yonda), about how well things are going with Count Tauru's big plan, when a messenger bursts into the room, with news of Tauru's arrest and imprisonment. The messenger identifies Sandra as an impersonator.
