The Bottom Line: A breathtaking collision of explosive secrets, psychological warfare and international intrigue, The Coded Crucifix is a terrorism thriller with extraordinary emotional firepower.
The Coded Crucifix opens with two fresh corpses in a Pamplona apartment and a ruthless killer slipping into the crowds gathering for Spain’s legendary Running of the Bulls. Author David A. Dummer, in his follow-up to Born of Bombs and Bullets, then turns back one week to reveal how Dr. Aaron Thornton, an FBI psychologist and crisis negotiator in his thirties, becomes an unlikely central figure in an international counterterrorism investigation.
Newcomers to the series will find that The Coded Crucifix works well as a standalone thriller. Readers of the first book will remember Thornton as a vulnerable American psychologist attempting to help others navigate the trauma of Northern Ireland’s Troubles. Now an FBI crisis negotiator, he returns to Europe carrying psychological wounds of his own. Summoned to England by MI5, Thornton reunites with former patient Tommy Magee, who warns that an Irish Republican Army (IRA) faction is planning a major operation in Spain with a mysterious mercenary known as El Gocho. His parting warning is even more unsettling: don’t trust MI5.
Nearly a quarter-century after Northern Ireland’s 1998 peace agreement, Dummer portrays an IRA faction still willing to use violence to end British rule. But why would Irish militants stage an operation in Spain? The question itself is enough reason to keep turning the pages.
With just seven days until Pamplona’s first bull run, British intelligence considers the IRA’s historical ties to Basque separatists, yet can identify neither the target nor the method. Worse, El Gocho has evaded identification for two decades despite suspected involvement in political assassinations and devastating government security breaches. Paired with ambitious MI5 analyst Sarah Maylor, Thornton is sent to Spain, where suspicious bank transfers lead them to fighting-bull breeder Ezequiel Naveros. An inquiry into financial irregularities has become a possible violent crime, even as the festival approaches.
Dummer makes Spain’s traditions an active source of tension rather than decorative scenery. At Naveros’s ranch, the owner patiently shows Thornton how to hold a bullfighter’s cape, then abruptly orders a young bull released into the practice ring. Thornton must use the lesson immediately to avoid its horns. The scene captures the novel’s recurring tension between control and vulnerability, particularly for a psychologist still struggling with nightmares and doubts about his professional fitness. Dummer also reprises the unconventional, multi-perspective storytelling that distinguished Born of Bombs and Bullets.
Where the earlier novel used character vignettes to illuminate Northern Ireland’s fractured society, the sequel gives that approach a larger international canvas. Frequent shifts in perspective occasionally slow the central investigation, but they also allow seemingly unrelated characters and events to acquire surprising importance.
The surrounding cast supplies conflicting loyalties and motives. Series fans will recognize Brianna Donovan, formerly a rising IRA figure and now the formidable leader of its Belfast crew. James Dwyer, whose technological expertise figured prominently in the previous novel, also returns. El Gocho, meanwhile, emerges as a particularly unsettling adversary whose disguises, criminal connections and extraordinary ability to evade detection make him difficult to anticipate, much less apprehend.
The case grows more intricate as an investigation in Argentina produces questions about Nazi escape routes, old records raise troubling issues about Spain’s Franco era, and the missing MI5 handler’s activities prove harder to explain. As in Born of Bombs and Bullets, Dummer explores how historical violence continues to shape subsequent generations, this time extending the theme beyond Northern Ireland to Spain’s political and familial divisions. Religious devotion and the contradictions between professed faith and actual conduct add another dimension.
Meanwhile, the stakes turn sharply personal as Thornton discovers that El Gocho’s reach extends far beyond Pamplona, forcing him to confront vulnerabilities that no amount of professional training can erase. The interlocking threads culminate in a satisfying but unsettling payoff, with unexpected reversals and a startling revelation that reward attention to seemingly incidental clues. Some may find the book’s procedural explanations extensive, but the crowded festival streets, precarious ranch, wartime mysteries and psychologically vulnerable protagonist give the story a distinctive identity that will keep series fans coming back for more.
Dummer has expanded the geographical scope and criminal stakes of his series without abandoning its emotional foundations. His strongest achievement is making each seemingly separate investigation alter the danger posed by the others. The past, in this thriller, is never safely buried.
