A lot of people finds the Old Testament as something boring; full of prohibitions, orders, rules, etc.
Surprisingly, there is a quite good adventure story there – The Book of Tobias (it’s part of Catholic and Orthodox canons only).

There were a father Tobit and his son Tobias – Jews of the Tribe of Naphtali. They were living in captivity in Assyria during 8th century BC. After pidgeon had shitted over Tobit’s eyes and made him blind, Tobit started praying for a death. Later Tobit remembered that one men in Media owes him money. So before upcoming death he send his son, Tobias, in order to regain the debt. Tobit found Tobias a companion for this long and dangerous journey: a mysterious – but responsible and wise – man named Azariah.

After arriving in Media, Tobias met a young and beautiful girl named Sarah, whom he has the right to marry. Unfortunatelly, the girl is possesed by demon Asmodeus, who had killed every man she had tried to marry.

Would Tobit regain his debt? Whould Tobias marry Sarah or be killed by Asmodeus?
And finally, who is Azariah?
