Deadly Sin

After retiring, criminal investigator Ruslan Bortnikov goes to a monastery located on an island in the White Sea. He becomes not a monk but a laborer. Ruslan has much to understand and contemplate. Why did his wife leave? Why are his relationships with his adult daughter not going well? And it wouldn't hurt to improve his health, weakened by work, away from the capital…

On New Year's Eve, Ruslan wakes up to the sound of a gunshot and finds the killed abbot. It turns out that even in a Christian community, strictly living according to God's commandments, there is no peace and tranquility.

There are only eight people on the island, not counting the former police officer. Ruslan must find out who among them is the murderer.
