One Split Second Themes
by Robert Dugoni
At heart, One Split Second wrestles with war trauma and PTSD, guilt that legal justification cannot soothe, cold cases that never stop hurting, staged evidence, local power, and family duty. It asks how people carry violence, loss, and inherited responsibility when the truth is buried or controlled.
Here you'll find each theme with concrete moments: Alvarez's PTSD and Buzz's Marine bond; Tracy, Jenny, and Curtis Parker's guilt; Jackie Parker's 1980 disappearance and Tracy's loss of Sarah; Alvarez framed by deer blood and the crazy Vietnam vet story; the sheriff's posse and county politics; Jenny following Buzz and the Almond sisters rallying. Symbols include Jan Oliva's cassette tape, deer blood, Vietnam-style trip wire and tin cans, and Buzz's Klickitat County Sheriff badge.
Major Themes in One Split Second
Vietnam War trauma and PTSD
The book ties Anthony Alvarez's behavior and the investigation's misreading of him to his Vietnam service and PTSD, while Buzz Almond's shared Marine experience shapes his empathy. Trauma persists through meds, nightmares, therapy, and the way others dismiss or exploit Alvarez.
- Alvarez's phone call and his tin-can perimeter recall Buzz's stories about Vietnam; he says someone tripped his wire.
- Buzz tells Ostertag that Alvarez is paranoid and distrustful because he is a Vietnam veteran, and Ostertag accuses Buzz of being overly sympathetic because he shared that experience.
- Alvarez tells Buzz nightmares make him drink to sleep, and his hand shakes as he asks about the next group session.
- Dr. Hernandez testifies Alvarez had Zoloft and risperidone for PTSD from Vietnam and THC in his system.
Guilt and the moral burden of justified violence
Characters who kill or are connected to killings find that legal justification does not bring emotional relief. Tracy, Jenny, and Curtis Parker all describe the absence of satisfaction or the lasting cost of violence.
- Tracy reflects that each justified killing in the line of duty took a piece of her soul and might one day haunt her.
- Jenny says being told the shooting was justifiable does not make her feel better and that she feels she has let her empathetic father down.
- Tracy tells Curtis Parker she killed the man who killed her sister twenty years later but got no satisfaction.
- Parker says he took no satisfaction from Sheriff Almond killing Anthony Alvarez.
Cold cases, unresolved loss, and legacy
The 1980 Jackie Parker disappearance drives the plot as a decades-old wound that never healed, and it parallels Tracy's loss of Sarah. Buzz's refusal to give up becomes a legacy passed to Jenny and Tracy.
- Goldman says Jackie Parker's body was never found, her yearbook space was left blank, and her parents eventually moved away because the grief was too much.
- Tracy resolves to pursue the forty-five-year-old Jacquelyn Parker cold case even if Jenny is allowed to retire.
- Jenny finds no paper Jackie Parker file but computer records show Buzz checked it out in 1994; they discuss DNA and CODIS and that Buzz never gave up.
- Jenny gives Tracy her father Buzz Almond's Klickitat County Sheriff badge, and Tracy accepts it; she closed his two remaining investigations.
Staged evidence, framing, and deliberate misdirection
The investigation against Alvarez is built on planted or staged evidence and rumors, while the real conspirators use the 'crazy Vietnam vet' narrative to hide Jackie Parker's murder. The book contrasts Buzz and Lydia's skepticism with Ostertag's pressure for a convenient suspect.
- Lydia argues the basement stepladder, open window, and single tennis shoe were staged; Buzz learns the blood evidence was deer blood planted to frame Anthony Alvarez.
- Alvarez tells Buzz someone tried to pin the crime on the 'crazy Vietnam vet'.
- Jan Oliva recalls one of the men on the tape saying he had deliberately directed the investigation toward Alvarez.
- Buzz tells Alvarez that supposition is not evidence and argues to Ostertag that Alvarez is the low-hanging fruit, warning that naming the wrong man loses momentum.
Local authority, vigilantism, and political power
The new sheriff's posse and county politics create a parallel power structure that threatens the rule of law and outside investigators. Authority is performed through armed presence, threats, and control of the official narrative.
- Three armed men claim they are doing what they were deputized to do by the sheriff of Klickitat County.
- Travis Beaumont warns Tracy not to impede his investigation, threatening her with jail.
- Nolasco warns Tracy that Beaumont believes he has ultimate authority in the county and has sworn in a posse; he doubts they will take well to another agency poking around.
- Marcus Kane lines the walls with posse members and runs one of the posse divisions; Dan dismisses two potential jurors who served on Beaumont's posse.
Family, duty, and belonging
The story frames duty through family inheritances—Jenny following Buzz, the Almond sisters rallying, and Tracy weighing her own family after Sarah's death. In the end, belonging and commitment to loved ones counterbalance the case's violence.
- Jenny insists she will do her job until her term expires and follows Buzz's instruction to handle Alvarez personally; the Almond family gathers at the farmhouse.
- Maria says 'We'll get through this' and walks into the courtroom with defiance; Sophia and Maria plan to look after Trey and Sarah.
- Tracy remembers Doc Crosswhite wanting to parent two independent and confident women and thinks she wants to parent Daniella the same way.
- Tracy tells Dan there is no place else she would rather be than beside him; Sam advises them to kiss good night and ask if there is any place else they would rather be.
Symbols and Motifs
Jan Oliva's cassette tape
A hidden record of the past and concealed evidence; whoever controls it controls the truth of Jackie Parker's abduction.
- Jan Oliva finds a cassette in her father's musical diary labeled December 4, 1980, on which two men discuss Jackie's abduction.
- She gives a copy to Detective Ostertag and later leaves the original tape for Anthony Alvarez; Ostertag keeps the tape, does not log it, and dies two days later.
- Tracy finds Oliva's cassette tape hidden in Alvarez's underground shelter beneath a hatch and tunnel.
- Tracy reflects that without the tape their argument relied on circumstantial evidence, and she needs the tape to ensure Jenny walks free.
Deer blood
Staged evidence and framing; a false trail that directs suspicion onto Alvarez and hides the real crime.
- Buzz learns the blood from Alvarez's trailer, the handprint, and Jackie Parker's clothing is deer blood, not human.
- Lydia concludes the evidence appears staged to lead the investigation toward Alvarez.
- Jan Oliva recalls one man on the tape saying he had deliberately directed the investigation toward Alvarez.
- Tracy testifies the blood trail and blood on Jackie Parker's clothing were deer blood, not human blood, and that she concluded this was an attempt to mislead the investigation toward Alvarez.
Vietnam-style trip wire and tin cans
Alvarez's trauma and paranoia, and a literal sign that someone entered his perimeter; it embodies the war that never left him.
- Alvarez's property is encircled by tin cans on wire, and he says someone tripped his wire.
- Buzz recognizes the rattling cans as a Vietnam-style trip wire and reflects that Alvarez was a tunnel rat.
- Alvarez reports his trip wire was hit and a thump on his trailer later.
- Tracy deduces Alvarez was a tunnel rat and finds a ventilation pipe, hidden hatch, and underground shelter.
Buzz Almond's Klickitat County Sheriff badge
Family legacy, duty, and closure; the passing of the investigative torch.
- Jenny gives Tracy her father Buzz Almond's Klickitat County Sheriff badge, and Tracy accepts it.
- Jenny says Tracy closed his two remaining investigations and plans to work with Will George while spending more time with Neil and the kids.
- Buzz's preserved photographs and file checks are recalled as aiding Tracy in cold cases.
