Behind the walls of a secluded Greek convent, a woman revered as a living saint was orchestrating something far darker than devotion — she was killing. Mariam Soulakiotis, one of history's most chilling and least-known female serial killers, lured the faithful with promises of spiritual salvation before stripping them of everything, including their lives. If you've never heard this true crime podcast case before, prepare to have your understanding of faith, manipulation, and evil permanently shaken.

In this episode of Dark Whispers: Serial Killers, Dark Whisper Studios takes you deep inside the Penitent Sisters of the Holy Fire convent in Greece, where Soulakiotis wielded absolute religious authority to abuse, starve, and murder vulnerable followers across decades of unchecked horror. We examine the psychology of a predator who weaponised faith as her instrument of control, the staggering number of victims — estimated at over 160 — who perished under her rule, and the painstaking investigation that finally brought her crimes into the light. From the grooming of desperate believers to the mass graves that shocked a nation, no detail is left unexplored.
