Killing of Guardia Real Agents

The killing of Guardia Real agents Rafa Díaz and Fonseca inside Sagrada Família marks the climax of Admiral Luis Ávila's mission to silence Edmond Kirsch's associates, transforming the basilica into a deadly trap where two highly trained royal bodyguards are murdered and Robert Langdon is forced into a desperate fight for survival.

The Ambush in the Sanctuary

After Robert Langdon, Ambra Vidal, and Father Joaquim Beña descend into the crypt to examine William Blake's book, Agent Díaz remains alone in the main sanctuary while Agent Fonseca steps away to make a phone call. In the darkness, Díaz receives a call from Commander Diego Garza, who warns him that the kidnapping story was false and instructs him to keep Ambra safe. As Díaz reaches inside his blazer to return the phone, two pale hands emerge from the blackness behind him, clamp down hard on his head, and wrench it to one side with blinding speed. Díaz feels his neck snap and a searing heat erupt inside his skull; then all goes black. The killer has dispatched the first Guardia agent silently, leaving Díaz's body on the floor with his head twisted grotesquely 180 degrees backward, his lifeless eyes aimed at the cathedral ceiling. The agent's gun is taken from its holster.

The Second Killing and the Flight Upward

When Father Beña returns from the crypt and discovers Díaz's body, his screams bring Langdon and Ambra rushing up from below. In the darkness nearby, a fierce struggle erupts, followed by a deafening gunshot at close range. A pained voice urges "¡Corre!" — Run! — and then a second gunshot explodes, followed by the heavy thud of a body hitting the floor. Agent Fonseca has been killed as well. Langdon grabs Ambra and pulls her toward the deep shadows near the sidewall, with Beña arriving a step behind them. A bright flashlight flares in the middle of the sanctuary, its beam swinging in their direction. Beña guides them into an opening in the stone, and they plunge into Sagrada Família's infamously treacherous spiral staircase — a narrow, circular shaft with a dizzying drop at its center and virtually no barrier, just an ankle-high inner lip.

The Confrontation on the Spiral Staircase

As Langdon, Ambra, and Beña climb the tight spiral, the killer enters the staircase below, his flashlight probing erratically up the center shaft. Langdon realizes they will never reach the top before the armed man catches them. He turns, plants his feet, and faces down the staircase. When the killer rounds the curve into view — a dark form running with both hands outstretched, one clutching the flashlight and the other a handgun — Langdon explodes from his crouch, launching himself feetfirst through the air. His heels drive into the man's chest with a powerful thrust, driving him back into the wall. Langdon falls hard, landing on his side, as his attacker crumples backward, tumbling down several stairs. The flashlight bounces and rolls to a stop, illuminating a metal object on the stairs between them: the gun. Both men lunge for it, but Langdon has the high ground and grasps the handle first, pointing the weapon at his attacker. In the glow of the flashlight, Langdon recognizes the salt-and-pepper beard and stark white pants: it is Admiral Luis Ávila, the navy officer who killed Edmond Kirsch at the Guggenheim.

Ávila's Final Assault and Fall

Ávila, his ribs broken by Langdon's kick, assesses his situation. His enemy holds both the weapon and the high ground, but Langdon's unusual grip on the gun reveals inexperience. Ávila shifts slowly onto his knees, feigning submission, while the ceramic pistol with which he killed Kirsch remains lodged in the back of his belt, loaded with its last remaining bullet. He opens his palm to show Langdon his tattoo, and when the professor's focus shifts briefly, Ávila lunges upward and to his left, moving out of the line of fire. Langdon fires on impulse, the bullet grazing Ávila's shoulder before ricocheting harmlessly down the stairwell. Ávila rolls in midair, drives his fists down hard on Langdon's wrists, forcing the gun from his hands and sending it clattering down the stairs. He yanks the ceramic handgun from his belt and points it at Langdon's chest, pulling the trigger. The gun roars with an unusual shattering noise — the barrel has exploded, built for only a shot or two. Ávila drops his weapon and lunges at Langdon, the two men grappling violently near the precariously low inner edge of the shaft. Ávila presses one leg against the outer wall, giving himself enormous leverage, and tries to muscle Langdon backward toward the hundred-foot drop. Rather than fighting the force, Langdon crouches, plants his feet, and launches himself into the air, arching his back out over the void. The sudden reversal of forces yanks Ávila entirely off balance. As Langdon arches away, he collides hard with a vertical face of stone on the opposite side of the shaft and crashes down on the lower portion of the spiraling stairs, striking his head. The last thing he hears before blackness sets in is a series of recurring thuds beneath him, each one farther away than the one before — the sound of Admiral Luis Ávila careening down the trash-chute-like shaft all the way to the bottom, where his body is later found by police, awkwardly splayed and illuminated by the beams of several flashlights.
