About the book: 2009 / The White Goose detective agency has a great team! The computer genius Vadka, the karateka sisters Murka and Kisonka, and the finance specialist Seva have every reason to consider themselves true professionals who can cope with any investigation. But Katka... The girl is younger than the rest of her companions, and sometimes it seems to her that the guys don’t take her seriously. But when the agency’s winged mascot was kidnapped right before her eyes on New Year’s Eve, Katka realized: the return of the fighting goose now depends only on her.
