It’s only a week left until summer vacation. Emil’s school class goes on a bike excursion to the sea, though for Ubbe not much is going well. His bike is rusty and rattles and has hardly any air left in the tires.

Luckily, it’s his birthday tomorrow and the friends in the detective agency decide to surprise him with a party. He also gets a new bike!

But already the next day the bike is gone and on the ground lies the lock, chopped. Who might have been so rotten and stolen Ubbe’s birthday present?
