This 2011 detective novel transports the reader to an ancient country mansion concealing secret passages and mysterious rooms, where people flock in search of miraculous solutions to their life’s problems.

The building itself is filled with complex mechanisms and optical illusions that skillfully mimic real magic.

The Mysterious House of Andrzej Kowalski

Polina Averina, a twenty-three-year-old woman who lost her home and job due to her ex-fiancé, Dmitry, desperately answers a newspaper ad for a housekeeper. She arrives at a secluded country mansion by commuter train, enduring the inconvenience of the journey, and is met at the station by a sullen, six-foot-tall driver, Vasily, in a vintage yellow car. The house’s owner, the elegant Andrzej Kowalski, hires Polina, surprising her with his insight. The new housekeeper is astonished by the mansion. A mechanical dragon’s head hangs on the dark green front door. Enormous grandfather clocks and crooked antique mirrors line the hallways, and a variety of doors, each with a striking variety of shapes, conceals mysterious rooms.

Soon, Andrzej reveals to Polina the secret of his work. Behind a hidden panel, cleverly concealed beneath a portrait of a gloomy old man in the gallery, lies a circular room containing hundreds of antique keys. Kowalski claims he selects a special object to solve his clients’ life problems by influencing their subconscious. Upon receiving a suitable ancient artifact, a client suddenly finds a way out of a difficult situation. Andrzej recounts how, in the castle of the wealthy Hungarian Kossuth, he once stumbled upon a unique artifact that emanated incredible power. Enticed by temptation, he stole the object with the help of the cunning Vasily, leaving behind a masterfully crafted forgery. Since then, he has feared persecution.

Arrival of guests and private detectives

Polina gradually settles into her new surroundings. She fires the lazy cook Vera and hires the good-natured cook Klara Ivanovna, keeps the place in order, and avoids the strange, taciturn gardener Armen, who always hides in the glass greenhouse. New Kowalski clients begin arriving at the mansion. An old friend of Andrzej’s, the domineering businessman David Daliani, arrives. He is followed by the depressed artist Irma Akhmetova, constantly accompanied by her domineering sister, Angelica. Taras Volovik, an envious and spiteful lawyer in a black suit, arrives on a third-party recommendation.

Following them, two men — Makar Ilyushin and Sergey Babkin — unexpectedly appear in the house. It turns out that Kovalsky secretly hired these private detectives to search for the previous housekeeper, Anatoly, who disappeared without a trace several months ago. Anatoly left all his belongings behind, including his cell phone, and seemingly vanished into thin air, leaving Andrzej and Vasily searching the surrounding forest in vain.

The next day, during Polina and Vasily’s routine trip to the market, their car is deliberately pushed off a bridge into the river by a speeding KAMAZ truck. The massive driver manages to cut the jammed seat belt with a knife and pull the girl from the sinking car, but then loses consciousness from blood loss and concussion. With the last of her strength, the girl pulls her rescuer to shore. Vasily is taken to intensive care in critical condition.

The disappearance of the owner and the secret of the basement

Returning to the mansion, Polina discovers Andrzej has vanished without a trace. The clients are visibly nervous, demanding the promised sessions. Makar Ilyushin informs the disgruntled guests that Kowalski is delayed on business. The detective begins posing as Andrzej’s apprentice and authorized deputy, promising to conduct individual interviews with each guest.

Ilyushin recounts to Babkin and Polina an ancient legend about a genie who gave a shepherd the key to the magical Green Door leading to an ideal world. Makar confidently asserts that a secret society of fanatical "gatekeepers" still exists in Europe, searching unsuccessfully for this passage. It was from them that Andrzej stole his most valuable relic. The detective theorizes that one of the "gatekeepers" tracked down Kowalski, entered the house disguised as a client, killed the housekeeper, caused the accident involving Vasily and Polina, and has now gotten to Andrzej himself.

That night, Polina, trying to unravel the mansion’s secrets, uses the small whistle key Kovalsky gave her and finds a passage disguised as a cloudy mirror in the wardrobe of an empty office. She descends a secret staircase into a dark freezer-like basement, where she stumbles upon a frozen, dead body. Panicked, she makes her way back to the library, where she encounters the detectives. It turns out that the body of the missing Anatoly is hidden in the basement.

Ilyushin’s sessions and the exposure of the killer

In the morning, Makar Ilyushin calls his clients one by one to the library. He quickly sees through the petty Taras Volovik, who only wants to elevate himself above those around him, and shamefully throws him out of his office. Makar then provokes Irma Akhmetova into a direct confrontation with her sister. Angelica has suppressed the talented Irma her entire life, skillfully instilling in her a false sense of guilt. After a harsh conversation with the detective, the dejected artist finds the courage to break these suffocating shackles and drive Angelica away.

David Daliani is the last to visit Makar. He insistently demands a magical object, hoping to use it to change the character of his unmotivated son, Alexei. Makar refuses to help, advising the businessman to relent and let the child go. In a blind rage, Daliani attacks the detectives. It turns out that David is the obsessive fanatic who has long sought the Green Door.

Daliani had previously bribed Anatoly, the housekeeper, to find a stolen artifact. Anatoly had indeed taken the ancient Key from Kovalsky, but wanted to blackmail David, demanding a huge sum of money for it. In a fit of rage, the businessman killed the housekeeper and hid his body in the freezer, but never found the artifact — Anatoly had forgotten it in the pocket of his jacket, which he had discarded before the fight. Later, David staged an accident for Vasily to eliminate the vigilant guard and search the basement undisturbed.

A deadly battle ensues in the library. A distraught David nearly overpowers Babkin and Ilyushin, preparing to deliver a fatal blow to Makar’s temple with a heavy object. At that moment, a bandaged Vasily, having secretly escaped from the hospital, bursts into the room. The enormous driver drops a heavy grandfather clock on the killer’s head, saving the detectives and Polina.

Kowalski’s Secrets and the Green Door

The bound Daliani is handed over to the arriving police. Suddenly, Andrzej Kowalski himself appears in the house. It turns out he never left: he’d been hiding in his own greenhouse this whole time, professionally disguised as the gardener Armen. Kowalski admits he was terrified of Angelika. Many years ago, at a resort in Poland, Andrzej and Angelika accidentally poisoned their mutual friend Robert with a powerful sleeping pill. The woman began blackmailing the young man, who cunningly faked his own death.

He jumped onto a hidden cliff ledge, escaped, changed his name, and fled to Russia. Seeing his former lover in his home, he panicked. But Ilyushin uncovers and proves the truth: Robert survived, and Anzhelika was simply cruelly manipulating Kowalski. Andrzej begs Polina’s sincere forgiveness. It turns out that her ex-fiancé, Dmitry, was his client. It was precisely through his instilled confidence that Dmitry deceived Polina, embezzling her money from the sale of her apartment and the newly built house.

Upon learning of this, a remorseful Kovalsky deliberately hired the girl as a housekeeper, sincerely wanting to help her restore her self-confidence and heal her from her destructive feelings of guilt. Irma Akhmetova is forever freed from her sister’s corrupting influence. Taras Volovik leaves empty-handed. A timid romantic feeling blossoms between Polina and Vasily, who saved her. Kovalsky gives the stolen magic key to Ilyushin as a token of his profound gratitude.

Makar Ilyushin steps out into the morning garden. He reflects on an ancient legend according to which the Green Door inevitably leads to a beautiful, ideal world. The detective heads to the greenhouse, where Kovalsky lovingly cultivates a dense thicket of maiden grapes every spring, disguising the old doorway of the local healer’s ruined hut. Makar takes out a heavy metal object, inserts it into the keyhole behind the foliage, turns it twice, and confidently steps through the Green Door, disappearing into the unknown.
