The Scarlet Godwins - Twenty-One

This is the final episode of The Scarlet Godwins, and the second
of Marley’s unsent letters. In it she is still waiting for Otto’s
second coming. She had been expecting him to come back sooner.
This twenty-first letter is Marley’s final revelation. She writes
in it, that if Otto doesn’t visit her in prison again, he’ll
never know what happened. But if he does come back, he will be
sworn to secrecy. Otto is nearing the end of his long walk. The
story of Izzy’s involvement in Marley’s case has come to its
climax. It is a climax that did indeed provoke Otto into a second
prison visit, this time without his daughter. It is during that
visit that Marley passes Otto her second ‘unsent letter’. She
recites the missing poem, Secret Scarlet, and tells Otto what
really happened to her sister. Finally, the question of whether
Otto should be sworn to secrecy is answered.
