Stolen Time - Vangelis Hatziyannidis

Selected for his knowledge of an ancient secret sect - Phi Beta Kappa - a young student agrees to spend two weeks in a Greek hotel with a group of six characters for the equivalent of five month's rent.

All they want is to interview him, they claim, about his beliefs and his past, but when he discovers a signature and dates written on a drawer in his room the young man becomes anxious. His unease increases when he finds a concealed room and its alarming contents.
