Margaret Devlin

Margaret Devlin is the wife of Jonathan Devlin and the mother of Katy, Rosalind, and Jessica. In the investigation into Katy’s death, she is both a bereaved parent and a person whose behavior and family history become subjects of police scrutiny. The detectives consider whether she might have caused Katy’s prolonged illness, but their suspicions remain unproved; after Rosalind confesses, Margaret’s refusal to believe in her daughter’s guilt becomes a defining part of the family’s aftermath.

Family and Background

Margaret grew up in Dublin and was known locally by her earlier surname, Kelly. A neighbor, Pamela Fitzgerald, recalled her as a respectable young woman whose life changed when she became pregnant by Jonathan. According to Fitzgerald, Jonathan had been a troublesome young man, but he found work and established a home after learning Margaret was expecting; they married, and Fitzgerald regarded the child’s arrival as the making of him. Her account offers a community’s warm, if conventional, picture of the Devlins’ beginnings rather than independent evidence about their private life.

Jonathan later told the investigating detective that he and Margaret had been dating for only a couple of months when they discovered the pregnancy. Both were frightened. He had once raised the possibility that Margaret might travel to England, but she was religious and already felt guilty about becoming pregnant. He said that he did not regret marrying her. Looking back after Rosalind’s confession, he connected that early decision to his present fear about Rosalind, while acknowledging how grave the family’s circumstances had become.

The family’s home and finances offered investigators no obvious sign of a material motive in Katy’s death. The Devlins lived modestly, had little savings, and were close to paying off their mortgage, but had no debts or overdue phone bills. Their records showed no suspicious financial activity and no life-insurance policy on Katy. These checks did not resolve who was responsible for her death, but they supplied no financial explanation for it.

Katy’s Illness and the Investigation

Katy had been born a couple of weeks early, but her early childhood was described in her medical record as ordinary. At eight and a half, she began suffering repeated gastrointestinal episodes, including cramping, vomiting, and diarrhea. One particularly difficult period brought three emergency-room visits in a month. An exploratory operation about a year before her death led to a diagnosis of idiopathic pseudo-obstructive bowel disease with atypical lack of distension: the doctors had not identified a clear cause for her symptoms.

Because of the unexplained illness, the detectives considered whether a parent might have been making Katy sick. Cassie Maddox raised the possibility of Munchausen syndrome by proxy, while also identifying reasons the available record did not fit the usual pattern. Margaret had left school at fifteen and worked in a biscuit factory before marriage, rather than having a known background around medicine. More significantly to the detectives’ theory, the hospital records showed that Jonathan, Rosalind, Vera, or a teacher had sometimes brought Katy for treatment instead of Margaret. Cassie reasoned that this pattern sat uneasily with a theory in which a mother sought attention from medical staff.

Those discrepancies did not clear Margaret. Cassie cautioned that a person might not fit a typical profile and wondered whether the other girls’ records would show a similar pattern of illness. In particular, the detectives considered whether Katy’s symptoms stopping in the spring might coincide with a change in Jessica’s health. Rob Ryan chose not to ask the family for the records immediately, fearing that doing so would alert them that they were under suspicion before the investigators had firm evidence.

The additional records supplied no confirmation of abuse or induced illness. Rosalind had been frequently taken to doctors for minor complaints as a baby but appeared to have been the healthiest of the three sisters, without major illness or injury. Jessica had spent three days in an incubator after the twins’ birth, later broken her arm in a fall at school, and been underweight from around the age of nine; both girls had had chicken pox and routine vaccinations. Rosalind had also had an ingrown toenail removed. Cassie concluded that the files showed nothing establishing abuse or Munchausen syndrome by proxy, while Ryan observed that they could not rule either possibility out. The distinction between suspicion and proof remains central to Margaret’s place in the investigation.

Katy’s Death and Margaret’s Response

When detectives came to tell the Devlins that a child’s body had been found at the archaeological site beside their estate and was believed to be Katy, Margaret was sitting in the family’s orderly living room. Jonathan told her that the visitors were detectives, then stayed apart from her as Cassie delivered the news. Margaret began to cry. The narrator read her response as unusually resigned, in contrast to the shock and disorientation the detectives often encountered when notifying families. That impression was part of the investigation’s human assessment, not proof that Margaret knew what had happened.

The family’s account placed Katy at home the night before she disappeared. She had attended ballet class in Stillorgan, returned with Rosalind, eaten dinner, walked a neighbor’s dog to earn money toward ballet school, and then spent the evening with her parents. She went to bed at her usual time. Jonathan said he checked that the house was secured before going to bed; the next morning, he noticed the front-door chain was off and assumed Katy had gone to her aunt’s for breakfast. Margaret, who got up later, initially made the same assumption, then called the aunt, Katy’s friends, and finally the police. These were the parents’ reported recollections, gathered after Katy’s body had been found.

Jonathan later insisted that Margaret loved their daughters and would never hurt them. When Cassie pressed him to distinguish between making Katy ill and killing her, he rejected both possibilities. The detectives’ questions placed Margaret under suspicion, but the records and conversations presented in the investigation do not establish her involvement in either Katy’s illness or death.

Rosalind’s Confession and the Family Aftermath

After Rosalind confessed to involvement in Katy’s murder, Margaret reacted with vehement disbelief. She maintained that Rosalind had been with her cousins and accused the police of targeting her daughter. She also blamed Ryan for having repeatedly asked Rosalind out, and claimed that Rosalind had expected Cassie to try to frame her. Her outburst was not a reconsideration of the evidence but a defense of the daughter she believed the detectives had wronged. The scene sharpens the contrast between an official confession and a mother’s unwillingness to accept it.

Jonathan’s response was more guarded and practical. He told Ryan that the family had faced bricks thrown through their windows and an insulting word spray-painted on their car, and that he might move after the motorway dispute was settled. He planned to send Rosalind to counseling as directed by the judge, although he had read that counseling might not change someone like her. Rosalind was due to begin music studies at Trinity in October; Jonathan intended to keep her living at home rather than pay for a separate flat, and to monitor her as far as he could. Margaret, he said, still believed Rosalind had done nothing and that the police had set her up; she called Rosalind sensitive.

At the same time, Jonathan planned to send Jessica to live with his sister in Athlone once the marks on Jessica’s wrists had healed. He described the move as a way to get her out of harm’s way, then bitterly recognized that the danger he feared came from her own sister. Margaret’s position is therefore shown through the consequences of her continued belief: while Jonathan tries to manage the risk inside the household and protect Jessica, Margaret remains aligned with Rosalind. The evidence does not give Margaret a later change of mind or reconciliation with the account of the crime.
