Ruth Deaver is a retired professor and the estranged adoptive mother of Henry. Her fading memories may hold a key to Castle Rock, Maine's unsettling past. Ruth is in a relationship with Castle Rock's long-serving sheriff, Alan Pangborn.
Ruth Deaver was married to Castle Rock, Maine's pastor, Reverend Matthew Deaver and they adopted a black child, Henry. When Henry went missing for eleven days in 1991, Matthew was found half-frozen and with a broken back while out searching. He died three days later.
By 2018, Ruth was suffering from a form of dementia, and Henry – who had moved to Texas – arranged for a nurse to care for her. When Henry returned to Castle Rock, he found that the nurse had been dismissed long ago, and that Alan Pangborn was living with his mother.
