Summary

Tristán, driven by his characteristic charm and persistence, works his contacts over several days to obtain Alma Montero's phone number. He calls and speaks with her niece, Marisa, who serves as Alma's caretaker. Using the pretext of a documentary about Abel Urueta and his unfinished film, Tristán secures a meeting at Alma's apartment near Parque México.

The building is an elegant Art Deco structure that survived the 1985 earthquake. Inside, the apartment is furnished with mid-century modern pieces—teak and rosewood—a curated space that contrasts sharply with Abel's cluttered, shrine-like home. Marisa Montero, a lacquered woman in her fifties with heavy makeup and red nails, greets them. She explains that her aunt, now eighty-seven, suffered a stroke years ago and is spending the winter in Acapulco, away from the city's pollution. Marisa claims she has relayed their questions to Alma and taken notes on her answers.

Montserrat immediately presses the conversation toward Wilhelm Ewers, noting that Alma financed Beyond the Yellow Door and dated the sorcerer. Marisa deflects, insisting this wasn't among the submitted questions. Montserrat pushes harder, revealing that Abel is dead—murdered—and that he claimed Alma had been in touch with him before his passing. Marisa denies this, but Montserrat's relentless interrogation, paired with Tristán's smoother approach, cracks her composure. She agrees to speak off the record.

Marisa reveals that Alma met Ewers at a party where he was reading palms. He was an aspiring actor and part-time fortune teller who charmed his way into Alma's favor. Alma financed his experiments—not screen tests for acting, but attempts to cast spells through the combination of film, light, sound, movement, and voice. Marisa references The House of Infinite Wisdom, Ewers's book outlining his magic system, which Montserrat has read. Ewers believed that ancient cultures embedded spells in pyramids and that film could serve a similar purpose.

The story darkens: Ewers started a cult and recruited followers. Alma initially loved it, believing in his magic and his charm. But Ewers became reckless—stealing corpses from cemeteries, pushing his magic too far. When he died, Alma destroyed his possessions, fearing that his fanatical disciples would misuse them. Marisa names two of Ewers's most devoted followers: Clarimonde Bauer, who kept reprinting his works until financial troubles stopped her, and José López, who still carries graveyard dirt and a chicken foot for casting hexes. López, it turns out, co-wrote Beyond the Yellow Door under the pseudonym Romeo Donderis.

Marisa also reveals that Ewers's runes still appear in graffiti around the city, and that Alma avoids Mexico City because she believes someone is still casting spells using Ewers's magic system—she recognized his runes on an abandoned building near the apartment. When Montserrat asks about Ewers's death, Marisa says only that it was reported as a mugging, then ends the interview.

Afterward, Montserrat tests Marisa by mentioning throwing nails behind their steps—a spell. Marisa's reaction—clenching her hands, a crooked smile—confirms Montserrat's suspicion that she's nervous. Montserrat declares something was
