A maniac has appeared in the Far Forest. Ruthless and elusive, he plucks the birds and burns their feathers to ashes. It seems even the Police Major Badger can’t stop it—yet it’s just about to hit a dead end: the junior assistant Badgercot has been removed from duty and is listed as a suspect, while the investigator himself is ready to practically give up. Lack of sleep, endless overtime his new colleague—special agent Supermouse—ensures for him, and suddenly a longing for family and comfort throws him off. But years of experience don’t disappear overnight, so Senior Bursuk gathers himself for the last case. It’s time to finally find out where the bird’s milk has gone, what a penguin has to do with Badgercot, whether it’s worth trusting your eyes when you see a ghost, what the authorities fear, and what the meaning is of the “no” that “no” is.
