About the book: 2017 / A man left the house and disappeared. Dissolved in space. A common story for a big city, where there are no watchful grandmothers on the bench, and children prefer to look into gadgets rather than around them. And what does it matter if the old swindler Mikhail Groys disappeared? Who will cry for him? But it turns out that there are people who care about him. Private detectives Makar Ilyushin and Sergei Babkin begin an investigation and quickly get on the trail of the kidnapper. Or does this trail lead to a dead end? Is the life of a swindler worth a precious tiara? A bird flying into a house is a bad omen. And if you yourself lured a frightened sparrow into a trap, but suddenly discovered a predatory and cunning owl instead, trouble is definitely inevitable. Will the bird catcher himself become a victim? Read about this in Elena Mikhalkova’s new detective story “Close the door behind the owl”».
