Chapter 16: Afterword – The Capture of the Boogeyman

⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

The Afterword is set in September 2019. Richard Chizmar receives a call from Carly Albright, who tells him that the Boogeyman has been caught — Joshua Gallagher, now 53. The chapter opens with Chizmar reflecting on the thirty-plus years since the killings: his marriage to Kara, their two sons, his cancer diagnosis and successful treatment, and the deaths of his parents and many friends. He also notes the limited success of the original 1990 book Chasing the Boogeyman, published in a small print run.

Carly later calls Chizmar with extensive notes from Lieutenant McClernan of the Maryland State Police. McClernan re-opened the cold case and systematically worked through a list of possible suspects. She eliminated others based on DNA or alibis before turning to Joshua Gallagher. McClernan discovers that Gallagher was adopted, which explains why his DNA would not have matched his parents’ profiles. Using a ruse—having Detective Janet Ellis, who resembles Gallagher’s college girlfriend Anna Garfield, approach him—McClernan elicits a physical reaction from Gallagher. He leaves fresh sweat on the chair armrests, and that DNA matches the blood trace from the Cassidy Burch crime scene.

Confronted, Gallagher confesses to eight murders: the four Edgewood girls in 1988 (including his own sister Natasha), plus three additional killings in later years. He admits there may be more. The chapter includes a lengthy prison interview between Chizmar and Gallagher. Gallagher describes his first violent impulse at age seven, his long struggle to control “the bad thing” inside him, and his methodical planning of the murders. He reveals that he killed his father Russell Gallagher after his father discovered him torturing a dog and grew suspicious. Gallagher staged the death as a suicide. He also explains that he cut off the victims’ ears as a signature and made the mask because “it’s what the Boogeyman wanted.”

The afterword closes with Chizmar and Carly visiting the grave of Detective Lyle Harper, who died in 2019. They place a wreath and flowers, and Chizmar tells Harper that they finally caught the killer. The chapter ends with their laughter echoing across the snowy cemetery.

Character Development

Richard Chizmar: Grown into a family man and cancer survivor, he remains haunted by the case. He shows empathy and confusion when confronting the killer, struggling to reconcile the normal-looking man with the monster.
Carly Albright: Now a senior writer at the Washington Post, she remains a fierce friend and a source of support. Her sassy manner persists, but she is also deeply affected by the case’s resolution.
Joshua Gallagher: Emerges as a chillingly complex figure. He is articulate, soft-spoken, and claims to have fought his violent urges for years. Yet he shows little genuine remorse. His explanation of his first murder thought at age seven and his confession to killing his father reveals a calculated predator.
Lieutenant McClernan: A persistent and clever investigator who uses psychological tactics and attention to detail to solve a three-decade-old case. She respects the victims and seeks justice, but also feels the weight of the years lost.
Lyle Harper: Though deceased, his role as the original lead investigator is honored. Chizmar notes that Harper took pride in being a good father more than a good cop.

Themes, Symbols, or Motifs

The Boogeyman as a mask: The killer’s self-made mask represents the persona he adopted to hide his humanity and to embody a folkloric monster.
Compartmentalization and the door: Gallagher repeatedly describes locking “the bad thing” behind a door, a metaphor for his psychological suppression of violent urges. The door fails when his compulsion overcomes him.
Adoption and identity: Gallagher’s adoption was kept secret, possibly contributing to a fractured sense of self and detachment from family.
Long hair as a trigger: The killer’s fixation on long-haired women stems from his feelings for Anna Garfield, his college girlfriend who broke his heart.
Nature vs. nurture: The interview explores whether Gallagher was born evil or made so by environment. He insists he had a normal childhood with no abuse, suggesting an innate compulsion.
Closure and memory: Visiting Harper’s grave and telling him the news provides a final sense of resolution. The act of speaking the killer’s name aloud—after thirty years of calling him the Boogeyman—marks the end of a traumatic chapter.

Why This Chapter Matters

This chapter is the climax of the entire narrative. It answers every outstanding question: who the Boogeyman is, how he was caught, why he killed, and what happened to the people affected by the case. It provides a psychological portrait of a serial killer that adds depth and horror to the story. The afterword format grounds the novel in reality, blurring the line between fiction and true crime. Finally, it offers a bittersweet sense of closure for the characters and readers, honoring the victims and the investigators who never gave up.

Study Questions and Answers

How does Lieutenant McClernan finally identify Joshua Gallagher as the Boogeyman?
McClernan re-examines old case files and learns that Gallagher was adopted, so his DNA would not match his parents’ profiles. She uses a detective who resembles Gallagher’s college girlfriend to unsettle him during a routine interview. Gallagher’s nervous sweat on the chair armrests provides a DNA match to the crime scene sample.
What does Gallagher reveal about his father’s death?
Gallagher admits he killed his father after Russell Gallagher discovered him torturing a dog when he was ten. The father grew suspicious years later and was about to go to the police, so Gallagher staged his father’s death as a suicide.
Why does Chizmar feel conflicted about the capture?
Chizmar is relieved the case is solved but disappointed that the killer turned out to be someone he knew — a seemingly ordinary man he once played basketball with. He struggles to understand how a person can commit such atrocities while appearing normal, saying he was “looking for a monster” but found “something else instead.”
