Завещание красного Сен-Жермена

An old aircraft designer is killed by villains who broke into his home in the middle of the night, and his granddaughter Kira manages to escape. The grandfather was the only close relative of the girl, and she is determined to find and punish his murderers. Discovering the first clue in her grandfather's secret archive, she tries to unravel the case herself. The thread stretches far into the past and leads to a mysterious figure — the enigmatic Richard Bertoni, who was called "the red Saint-Germain." Now, many years later, someone is killing his best students — and the life of young Kira, tirelessly uncovering old secrets, is also under threat…

In each novel by Ekaterina, the world's mysteries of the past unexpectedly manifest in the present. The book's heroes, for example, investigate the crash of an airliner similar to the Titanic; receive strange letters with excerpts from Dyatlov's diary while staying at a ski base in the mountains; find the diary of Kennedy's assassin or learn interesting facts about their ancestors' lives, such as that they were acquainted with the poet Nikolai Gumilyov. All these mysteries of the past turn out to be closely intertwined with the heroes' lives and, one way or another, influence their fate.
