A character which shows determination

In the novel Prisoner of Zenda by Anthony Hope, the character that showed great determination is Rudolf Rassendyll.
When the King was kidnapped, Rudolf Rassendyll was determined to free the King from being imprisoned in Zenda Castle. He had agreed earlier to only impersonate as the King for the coronation but after the King was kidnapped, he continued his impersonation. He planned to rescue the King.

In his attempt to rescue the King, he had to risk his life a few times. The Famous Six was sent to kill him when he went to see Antonette at the house she was staying, and Rupert of Hentzau stabbed him from the back when he refused to accept bribe offered by Duke Michael. He was again shot by Rupert on his shoulder when he ran after Rupert for killing Duke Michael.

Rudolf Rassendyll’s honesty was also put into a test when he fell in love with the beautiful Princess Flavia. Instead, he sacrificed his love for her because he was determined to rescue the King. His mission was to return back the throne to the King so that Ruritania would not fall into the hand of the evil Duke Michael and his Famous Six.

In the end his determination led to his success in rescuing the King.
