Jonathan Michael Devlin

Jonathan Michael Devlin is Katy Devlin’s father and a leading figure in the Move the Motorway campaign. As investigators connect Katy’s death with the disappearances of Peter Savage and Germaine Rowan, Jonathan becomes both a grieving parent demanding answers and a guarded witness whose responses raise questions without establishing what he knows.

Identity and Public Position

Jonathan is associated with the campaign against the proposed motorway and is described as someone Peter Savage might have joined had he lived. That connection makes the earlier disappearance case more than a remote historical matter: Peter’s parents have remained in their home in the hope that he might return, while Jonathan’s campaign places him in the same present-day landscape of Knocknaree and its unresolved losses.

His family life also brings him into contact with the investigation through Katy and Jessica. When the detectives speak with him, he is intensely focused on finding who killed Katy. That demand is sincere in its urgency, but it does not settle whether his own knowledge of the family’s past is complete.

The Threat Calls and Jessica’s Account

Jonathan reacts to anonymous calls connected with the campaign with a mixture of misery and defiance. He says he had been pleased to receive them because they seemed to show that the campaign was a genuine threat, but now wants the detectives to identify the caller and determine whether that person had anything to do with Katy’s death. His response links the political conflict to his personal fear, while leaving the caller’s identity and any connection to the murder unresolved.

Jessica contributes a fragment of her own: she says that a man frightened Katy. When Cassie Maddox gently asks whether anyone else had frightened her, Jessica reaches for Cassie’s sleeve and asks whether the situation is real. Later, Jessica reports seeing a man speak to Katy on the road as the sisters were returning from a shop. She does not identify the man as the caller, or connect him to Jonathan; her account supplies a possible lead, not a resolution.

The handling of Jessica’s statement underscores how difficult it is to establish what she herself remembers. When Rosalind begins to explain what Jessica supposedly saw, Rob Ryan stops her, noting that the evidence needs to come from Jessica rather than through another person’s account. Rosalind encourages Jessica to speak, but Jessica initially withdraws and says she does not remember. When she later describes the man, she looks toward Rosalind rather than Rob. Her account is followed by a further difficulty: asked when the meeting occurred, Jessica corrects the suggestion that Katy had gone away, saying that Katy was killed, then loses focus before she can supply a time. The testimony raises the possibility of an unknown man in Katy’s life without providing a reliable identification or chronology.

Interrogation and the Earlier Disappearances

In a later interview, Jonathan sees the investigation room’s wall of photographs and asks whether he is under arrest and for what. Cassie Maddox gives him the formal police caution; Rob Ryan explains that it is routine and that they want to update him on the investigation. The exchange sets the interview’s tension: Jonathan is wary of the questioning, while the detectives are trying to move between Katy’s case and the older disappearances.

Cassie brings up Peter Savage and Germaine Rowan, known as Jamie, and describes the lasting effects of their disappearance on their families. Peter’s parents could not bring themselves to move away, even when his father received an attractive job offer elsewhere. Jamie’s mother kept her room unchanged and continued dusting it every Saturday. Cassie then asks Jonathan what happened on 14 August 1984, the day Peter and Jamie vanished. Jonathan says that he has already told the police everything he knows.

Jonathan denies knowing what happened to the children and rejects the suggestion that he and the other boys committed murders. He insists that he wants to know who killed Katy, not to discuss Peter and Jamie. His response keeps the two cases in conflict: the detectives believe they may be connected, because failing to investigate that possibility could allow Katy’s killer to escape notice, while Jonathan presents the earlier case as something he cannot explain.

Katy’s Illness and the Questions Left Open

Cassie turns the interview back to Katy and lays out her medical history: four years of unexplained gastric illness, which ended after Katy told her ballet teacher in the spring that it would stop. The medical examiner had found no sign of an underlying problem. Cassie argues that the pattern points to poisoning by someone with daily access to Katy and whom she trusted; she further suggests that Katy stopped taking what was making her ill after gaining another chance at ballet school, perhaps threatening to tell someone.

Jonathan’s face turns markedly pale as Cassie presents this account. Rob Ryan reads the change as a sign that Jonathan knows something, but the interview evidence does not itself establish what that knowledge is or whether he participated in any harm. Jonathan’s reaction therefore functions as an investigative turning point rather than proof: it sharpens the detectives’ suspicion while leaving the central question about his knowledge unanswered. His repeated demand to find Katy’s killer sits beside his refusal to claim knowledge of the old disappearances, making him a figure suspended between the family’s need for answers and the investigation’s unresolved suspicions.
