Теория бобра

In the final part of the trilogy "The Rabbit Factor," the main character — former insurance mathematician Henry Koskinen, who by chance becomes the owner of an adventure park — finds himself in a complicated situation once again.
After moving in with his beloved Laura and her school-age daughter Tuuli, his firm belief in common sense and order faces the harshest trial…
At the same time, he becomes the target of "hostilities" from a criminal owner of a competing adventure park, acting without regard for the law…
Perhaps this time the "beaver theory" will be the saving grace?
