Help Its Vengos Visible Agent '000'

Athanasios Bobas is a secret agent in training, code-named Thou-Vou. He studies at a spy school named after James Bond. He is trained in martial arts, sharpshooting, and various sports, but he is thoroughly inept. His trainer is annoyed with him, and gives him low performance scores. In order to graduate and receive his degree, Thou-Vou has to successfully complete three missions. He has to put in practice what he has learned so far. He is to be rated with a grade from 0 to 9. His grades will form the three numbers of his new code-name. His first mission involves the beautiful daughter of a cantor. The girl is having a secret affair, and Thou-Vou has to find out who her lover is. His second mission involves a fashion company. Someone has been stealing its design patterns and Thou-Vou has to uncover the culprits. The third mission is to recover a secret document which has been hidden away in a cake. Thou-Vou fails spectacularly in each mission and is rated with 0. He graduates with the disappointing number of 000.
