In St. Petersburg's gray suburbs, loneliness hits hard. The elderly Tamara Samsonova desperately tries to fill the void left by her husband's sudden disappearance by renting out a room. But the tenants never hang around. Is it due to the bleak surroundings? Is it because Tamara herself is becoming more and more eccentric? Or is it connected to the mutilated corpses and occult signs that are found in the area? Listen to the hair-raising story of one of the 20th century's most brutal serial killers, who over two decades killed, dismembered and possibly ate its victims.

From Podimo and Vespucci — this is The Darkness Vaults, released weekly on Wednesday.
