Tripwire was published by Putnam in 1999, the third Jack Reacher novel. The book is significant in the series for beginning to develop Reacher’s personal history — particularly his relationship to his father, a Marine who served in Vietnam — while maintaining the thriller structure that the first two novels established.
Reacher is digging swimming pools in Key West (one of his periodic manual labor jobs) when a private investigator arrives asking questions about him. The PI is murdered before Reacher can find out who sent him. Following the trail back to New York, Reacher discovers that an old army colleague — the elderly father of a woman he once cared about — hired the investigator to find him. The old man is dying, and his last wish is to discover what happened to his son, an army pilot shot down in Vietnam whose remains were never recovered.
The investigation leads into a conspiracy involving falsified military records, stolen funds, and Victor Hobie — a Vietnam veteran turned loan shark who has built a criminal empire and who eliminates threats with a prosthetic hook that has replaced his burned-off hand. Hobie is one of the series’ most memorable villains: intelligent, patient, and genuinely frightening in a way that militia leaders and drug dealers are not.
The Vietnam background gives the novel thematic weight unusual for the series: questions of duty, sacrifice, and the long consequences of war animate the plot beyond its surface mechanics.
