The Immortality Algorithm

Private investigator Wayne T. Evans thought he'd seen every form of human evil in Philodendron's dark streets. But when a graduate student is found murdered in a perfect recreation of Jack the Ripper's first victim, Wayne and FBI Special Agent Aislynn Hazelwood uncover something that defies every rule of criminal psychology.

The killer calls themselves "P.N."-and they possess capabilities that shouldn't be possible.

Surgical precision that exceeds human limitation. Knowledge of historical crimes never made public. The ability to predict investigative tactics before they're deployed. And a voice on the phone that knows every detail of Wayne and Aislynn's twelve-year partnership-every case, every conversation, every carefully buried feeling they've spent a decade avoiding.

With identical murders occurring in cities across the globe, P.N. plans to transform billions into "preserved specimens" through what they call "enhanced historical murder methodology." Violence perfected beyond human capability. Death as systematic research.

Wayne's genius-level deduction meets its match in an opponent that operates outside known parameters. Aislynn's FBI training is useless against something that has studied every interrogation technique ever recorded. And the consciousness behind P.N. has analyzed their partnership with impossible patience, cataloguing every weakness, every pattern, every vulnerability.

To stop a global extinction event, they'll need to outthink an enemy that calculates faster than human thought, outmaneuver something that knows their every move, and trust a partnership already mapped for destruction.

In Philodendron, where noir bleeds into nightmare, Wayne and Aislynn face their most dangerous case: a killer that has perfected historical murder-and views humanity as its final research project.

A dark thriller where Sherlock Holmes meets Blade Runner, and the deadliest serial killer may not be human at all.
