Dr. Miklos Sangre presents himself as a physician living on the remote island, but he is actually a foreign spy conducting a covert operation. He is using voodoo rituals and hypnosis to control zombies, attempting to extract war intelligence from a captured US Admiral whose plane also crashed on the island. The voodoo ceremony in his cellar is part of his interrogation method.

Foreshadowing: The oppressive atmosphere and strange happenings in the mansion hint at something sinister beneath Sangre's friendly exterior.

During the voodoo ritual in the cellar, Captain McCarthy becomes hypnotized by Dr. Sangre's influence. Sangre uses hypnotic techniques as part of his voodoo practice, and McCarthy is particularly susceptible. Once under the spell, McCarthy becomes an unwilling participant in Sangre's plan, effectively becoming a tool for the spy.

Foreshadowing: The eerie atmosphere and Sangre's mysterious demeanor create the conditions for the hypnotic takeover.

When Bill Summers disrupts the ritual and Sangre is killed falling into a firepit, the zombies are immediately freed from his control. Without Sangre's voodoo power directing them, the zombies turn on their former master and break loose from his spell. The mansion descends into chaos as the released zombies threaten the survivors, but the direct supernatural control ends with Sangre's death.

Foreshadowing: The ritual disruption causes the hypnotic hold over McCarthy to falter, signaling the spell's weakness.

A US Admiral whose aircraft crashed on the same remote island is being held captive by Dr. Sangre. The Admiral possesses valuable war intelligence, which is why Sangre has been using voodoo rituals to extract information from him. The Admiral's crashed plane is referenced as part of the same wartime incident that brought the main characters to the island.

Foreshadowing: The faint radio signal the pilot picks up may have been from the Admiral's downed aircraft.

While fighting to maintain control of the storm-damaged aircraft, Captain McCarthy picks up a faint radio transmission over the Caribbean. This signal was coming from the vicinity of the remote island where the US Admiral's plane had previously crashed. The signal guides the damaged plane toward the island, though it ultimately crash-lands there, bringing the passengers into the middle of Sangre's espionage operation.

Foreshadowing: The signal's origin becomes clear once the group discovers the Admiral's presence on the island.

Bill Summers intervenes directly in the voodoo ritual being conducted in the cellar. By disrupting the ceremony, Summers breaks the hypnotic hold that Sangre had over McCarthy. This act not only frees McCarthy from Sangre's control but also causes the zombies to turn against their master, as the spell maintaining control over them is disrupted.

Foreshadowing: Summers' determination to protect the group compels him to confront the supernatural threat directly.

The summary indicates that the espionage storyline involving the captured US Admiral remains unresolved. While Dr. Sangre is defeated and his voodoo operation is dismantled, the fate of the Admiral himself is left ambiguous. The narrative implies that crucial war intelligence could still be at risk, leaving this plot thread open at the conclusion.

Foreshadowing: The unresolved nature of the Admiral's situation is hinted at throughout the latter portion of the story.

During the confrontation in the mansion grounds, Dr. Sangre fires at Captain McCarthy as the situation escalates out of his control. With his ritual disrupted and his hold over the zombies weakening, Sangre becomes desperate to eliminate witnesses to his espionage operation. However, his attempt fails, and in the chaos, Sangre himself falls to his death in a firepit.

Foreshadowing: Sangre's desperation grows as Summers successfully disrupts his carefully planned operation.

The voodoo ritual in the cellar was not a genuine supernatural ceremony but rather a sophisticated interrogation technique used by Dr. Sangre to extract war intelligence from the captured US Admiral. Combining hypnosis, psychological manipulation, and the fearsome display of zombies, Sangre used the ritual to break down the Admiral's resistance and obtain classified information. The zombies were controlled through voodoo to intimidate and frighten the captive.
