A Suspect Meets an Expert

A Suspect Meets an Expert
Initial suspicion
Mackenzie questions Hunter at Sally Palmer’s farm about their relationship and why he came there without first calling her. Hunter’s answers make him look like a possible suspect, while his knowledge of the dog’s wound reveals more expertise than he has admitted. Their first exchange is shaped by mutual caution rather than trust.
A concealed professional past
Mackenzie discovers Hunter’s forensic anthropology career and confronts him for withholding it. Hunter insists that he is now a general practitioner and does not want to return to his former work. Mackenzie, however, sees an investigator’s rare resource in front of him and asks for assistance identifying the victim.
Terms of Limited Help

Terms of Limited Help
Cooperation on Hunter’s terms
Hunter agrees to help identify the body but draws a firm boundary around his participation. At the scene, his explanations of maggot development, decomposition and skin slippage give the police practical leads. The evidence earns him a measure of professional respect from officers who had initially treated him as an outsider interfering in their work.
The boundary begins to erode
Mackenzie recognizes the value of Hunter’s observations and asks for further help, including an examination of the dog. Hunter resists being drawn into every stage of the inquiry, while continuing to answer questions that might protect a missing woman. The partnership advances through necessity, without either man fully relaxing his suspicion of the other.
Clashes over the Search

Clashes over the Search
Competing judgments
Hunter believes that the killer’s traps and animal signs may reveal more than the police are willing to acknowledge. Mackenzie has to balance that possibility against the risks of public panic and the need to protect searchers. Their disagreement becomes especially sharp when Hunter argues that people should be warned about the dead animals that may mark intended victims.
Professional caution versus urgency
Mackenzie withholds details and tests Hunter’s alibi, reminding him that investigators must consider everyone, including the doctor helping them. Hunter resents being treated as a suspect while also understanding why the questions are necessary. Their alliance works because each man supplies what the other lacks, but its foundations remain strained by secrecy and the shrinking time to find Lyn.
A False Suspect and Lost Time

A False Suspect and Lost Time
The arrest of Ben Anders
Police arrest Ben Anders after a report places his car near Jenny Hammond’s home and equipment in his vehicle seems to fit the killer’s methods. Hunter objects, believing the information may come from Carl Brenner, but Mackenzie resists the accusation without corroboration. When Anders is released, the lead collapses without bringing the police closer to Jenny.
A dangerous disclosure
Hunter confronts Carl Brenner and learns that his family covered for his poaching activities. He passes the information to Mackenzie, but admits that he has already told Brenner the victims were kept alive for days. Mackenzie is furious: the disclosure may alert a suspect to the police’s understanding of the pattern and could put Jenny in greater danger.
Evidence Forces a New Course

Evidence Forces a New Course
The official operation misses its target
Mackenzie organizes a tactical raid on the old windmill, acting on Hunter’s information about the Brenners and the suspected animal-trapping operation. The windmill is empty, and the police find no sign of Jenny. Hunter has kept a further discovery to himself: the location and traces that will eventually lead him to the old air-raid shelter.
The partnership reaches its limit
Hunter finds Jenny and Tom Mason before the police can, then rushes her back for emergency treatment. Mackenzie’s investigation has not stopped the abduction, but its resources and response remain essential in the aftermath. Their partnership ends not with complete agreement, but with a shared recognition that specialist insight and police authority both mattered—and that neither could undo the costs of delay.
