An Unresolved Instinct

Suspicion Without a Case
Landon’s Doubts
Landon remembers that Edward’s circumstances around the missing wives felt wrong, yet investigators could not connect him to either disappearance.
A Legal Barrier
The old files contain gaps, strong alibis, and no bodies. The detectives’ intuitions cannot substitute for admissible evidence, leaving the cases dormant.
Duan Holds Back

Balancing Urgency and Fairness
A Recognized Risk
Duan realizes that Kim’s mother is planning to marry a former suspect. He chooses not to tell Kim until he verifies that this is the same Edward Villarosas.
The Cost of Caution
His silence protects the inquiry from premature confrontation but later damages Kim’s trust. The novel makes the investigator’s restraint both professionally understandable and personally painful.
The Report’s Gray Areas

A Nurse Reads the Evidence
Records Without Conclusions
Kim studies the investigation report and notices that it contains many details but no definitive finding. She approaches the case as someone trained to seek a diagnosis supported by data.
Competing Methods
Duan explains that investigators must follow leads even when resources are limited. Kim sees why instinct matters, but insists that suspicion alone cannot justify condemning Edward.
Green’s Word Is Not Enough

A Powerful but Vulnerable Claim
The Accusation
Green says Edward hired him to kill the wives. The statement appears to explain the disappearances but comes from a man serving a life sentence.
The Search for Support
Duan insists that the team needs more than Green’s word. Financial withdrawals, call records, and searches for remains become necessary to transform an allegation into a case authorities can act upon.
Physical Evidence Found

Suspicion Gains Ground
Search Results
Authorities find remains where Green directed them. The discovery gives his statement independent physical support and makes official action possible.
Justice in Motion
Police move to question Edward and prepare murder charges. The evidence does not replace due process, but it resolves the central evidentiary obstacle that kept the old cases open.
