The Scarlet Godwins - Twelve

Marley prays for the strength to tell Otto all she knows. She
laments the fact that she made a vow not to use foul language;
she could have made use of a few choice words. In this letter she
manages (more or less) without them, as she recounts, from her
point of view, what happened on the last day of Charlotte’s life.
Still walking along a beach, Otto is thinking about a day in
2016, when he was left for dead. From her prison cell, Marley had
been denying that she'd had anything to do with the murder of her
sister. As Otto’s mind wanders to the most damning evidence
against Marley, he reflects on the reasons why he finally decided
to correspond with her.
