Sullivan’s Uneasy Account

Sullivan’s Uneasy Account
A missing interval
Jamie Sullivan says he stayed home after Luke left, but his grandmother reacts when he claims no one else came by. His account has a small gap that Falk notices.
Suspicion grows
A fire-service report shows Sullivan was away when his grandmother activated an emergency alert. His concealed trip makes him a plausible suspect, though it does not establish that he went to Hadler Farm.
The Secret Relationship

The Secret Relationship
An unexplained journey
CCTV places Sullivan in a back alley shortly before the murders, deepening suspicion that he was hiding his movements. He has already lied about being at home.
A personal motive for silence
Dr. Leigh admits that he and Sullivan were lovers and that they were together that afternoon. Fear of prejudice, not participation in the murders, explains Sullivan’s concealment.
Dow’s Name on the Note

Dow’s Name on the Note
A promising lead
Karen’s receipt carries the word Grant, which appears to implicate Grant Dow. His hostility toward Luke and plans to inherit Mal’s land give the suspicion apparent weight.
An ambiguous clue
Falk questions Dow, but no solid evidence places him at the murders. The clue’s meaning changes when Falk recognizes that Grant refers to a financial grant, not the man.
Mal’s Changing Testimony

Mal’s Changing Testimony
A late claim
Mal Deacon says he was on the phone during the shootings, a detail omitted from his earlier account. The new statement initially raises questions about whether he witnessed more than he admitted.
Memory erodes certainty
His dementia makes the story unreliable, and a pharmacy worker supports the call. Falk’s anger at Mal has helped him mistake personal grievance for evidence.
The Principal Under Suspicion

The Principal Under Suspicion
A hidden financial crisis
Falk learns that Whitlam gambled heavily and stole the school’s grant money to ease dangerous debts. Karen had found the discrepancy and was preparing to expose it.
The clues align
Whitlam’s access to the school ammunition, the concealed bicycle, the truck marks, and the grant paperwork turn scattered details into a single account. The sympathetic principal emerges as the killer.
