A practical union
Roger explains that Moira married Jasper while the criminal group faced pressure from American police. The marriage gave her a new social identity and helped the group evade attention.

Fear in the Household
A story of threatened murder
Moira tells Bobby that Jasper is trying to kill her through staged accidents. She claims to fear for her life and gives examples that sound plausible in the context of the Grange.
The marriage turned into evidence

The truth beneath the marriage
Roger’s letter explains that Moira and he were partners who used Jasper’s profession and new life in England as cover. Jasper did not know that his marriage sheltered a wanted criminal.
Intimacy used as camouflage
