I nona (1981)

Under everyone's noses, the mysterious blonde gambler, Lida, and her stylish, ever-watchful lover, Petros, have made a fortune by winning large sums of money at the Casino of Mount Parnitha. As a result, the suave Italian mobster, Davi di Redicolo, enlists the help of the great private investigator, Thiseas Doxapatris, and his right-hand man, Agent X2, to shed light on the case of the never-losing duo, intent on getting them out of the way. Without a doubt, a nefarious third person is behind Lida's infallible strategy; nevertheless, providing proof of foul play, let alone supplying evidence of an unbreakable psychic link with a spiritual helper during betting, is easier said than done. Can Thiseas master the art of telepathy? Will he ever discover the lair of the "Godmother", the elusive medium?
