was suspected to be behind the “theft of century”: theft of the famous Mona Lisa by Leonardo da Vinci. The police, however, could not produce any evidence against Mr. Alfredo. Shortly before his disappearance, he received a mysterious letter, in which he was asked to return the painting to Italy for 500 thousand million lire. Upon receipt of the letter, the art dealer turned to the police, but no action was taken. Jerry Alfredo mysteriously disappeared a few days after and eventually police had forwarded the case to the special department which has been dealing with some of most difficult crimes. Special Investigations Unit is on the case and, if found, they must bring back the painting.
