It seems that the robbers received help from the inside. When it turns out that the B&B was paid for with the credit card of an employee of the diamond dealer, the case seems to be solved quickly. Romeo and Marion are faced with a report of dating fraud. A fictitious person has swindled the victim out of thousands of euros.
