The death of Petar Popov, a Bulgarian billionaire and industrial magnate, marks the starting point of the investigation detailed in Book 1: “A Legacy of Shadows and Redemption.”

Popov was found deceased inside his private residence in the Veliko Tarnovo region. Initial reports classify the incident as homicide, though the exact circumstances surrounding the event remain unclear.

The property showed signs of disturbance.

Not forced entry.

Disturbance.

Selective areas within the mansion appeared to have been accessed with intent. Certain rooms remained untouched, while others indicated targeted activity—suggesting the perpetrator was not searching randomly, but knew what to look for.

What was taken has not been officially disclosed.

Independent findings suggest the removal of specific documents.

Prior to his death, Popov had been conducting a private and highly confidential investigation into an object referred to only as “the key.” Evidence indicates that he had compiled extensive records related to this subject, including connections, transactions, and unidentified entities.

These records are currently missing.

No verified copies have been recovered.

Popov's known associates place additional pressure on the case. His past relationship with Vladislav Ivanov—once a close ally, later a rival—positions Ivanov as an early suspect. However, no formal charges were brought forward.

Instead, parallel actions emerge.

Following the incident, Ivanov initiates a private investigation, recruiting Boris Ognen and redirecting the inquiry beyond Bulgaria. This shift expands the scope of the case, linking it to international elements and individuals previously unconnected to Popov.

The official investigation remains active, though limited information is publicly available. Multiple inconsistencies exist across reports, including timeline gaps, incomplete evidence logs, and restricted access to key locations.

The case is considered compromised.

Its resolution remains uncertain.
