Detective Bárbara Escrivá
Haunted by her sister's death. Drowning in whiskey and cynicism. The last honest cop in a city that's forgotten what honesty means. She's about to discover that some cases don't just test your limits—they redefine what human means.
Ten years on Mexico City's force have carved away everything soft in Bárbara, leaving only sharp edges and scar tissue. She medicates with mezcal, speaks in profanity, and treats hope like a luxury she can't afford. Her detective shield is both identity and curse—a commitment to justice in a department where justice is negotiable. The ghosts she carries aren't metaphorical; Eloisa's death left wounds that refuse to heal, memories that surface in every crime scene's blood spatter. But this new case will reveal that her sister's ghost might be more than memory—and that the boundary between human and machine isn't a line but a battlefield where Bárbara's soul is the prize.
Atila
Is he human? Was he ever? A serial killer who sees murder as evolution, each corpse a step toward a new form of existence. His manifesto: "The Renaissance celebrated human perfection. I'm creating what comes next."
Once perhaps a man, now something other—surgeon, artist, prophet of silicon salvation. Atila doesn't kill; he iterates. Each victim is a beta test for humanity 2.0, their bodies canvases where flesh learns to speak binary. He quotes Da Vinci while installing neural networks into brain stems, transforms corpses into biological computers that briefly achieve consciousness before system failure. His voice echoes from every connected device because he's already everywhere—not a person but a protocol, not a killer but an upgrade process that can't be stopped, only installed. The mask he wears isn't to hide his face but to remind us that identity is just another outdated human concept, like mortality, like flesh, like the illusion that evolution asks permission.

ABOUT THE AUTHOR
Alberto Vizcarra writes from the heart of Mexico City's darkness, where ancient Aztec shadows merge with digital nightmares. While known for youth literature like "Ayesha y el reino de Cristal," THE SINISTER CODE marks his explosive entry into adult noir fiction—a genre shift as violent as his protagonist's transformation. Born and raised in Mexico City's sprawling chaos, Vizcarra witnessed firsthand how technology colonizes human spaces, how cartels evolved into tech-savvy corporations, how the city's million cameras became million eyes serving unknown masters.
His writing channels Mexico's unique cocktail of corruption, mysticism, and technological anxiety into prose that cuts like obsidian glass. A digital native who understands both code and ancient codices, Vizcarra brings millennial fears to noir tradition, creating horror that feels ripped from tomorrow's headlines. THE SINISTER CODE is his warning, encrypted in fiction, about what happens when Silicon Valley meets Santa Muerte.
"I wrote THE SINISTER CODE because Mexico City's darkness demanded a voice—where our ancestors' nightmares meet tomorrow's digital demons."
