The main suspect was Dr. Marcel Petiot, a handsome, charming physician with remarkable charisma. He was the “People’s Doctor,” known for his many acts of kindness and generosity, not least in providing free medical care for the poor. Petiot, however, would soon be charged with twenty-seven murders, though authorities suspected the total was considerably higher, perhaps even as many as 150.
Who was being slaughtered, and why? Was Petiot a sexual sadist, as the press suggested, killing for thrills? Was he allied with the Gestapo, or, on the contrary, the French Resistance? Or did he work for no one other than himself? Trying to solve the many mysteries of the case, Massu would unravel a plot of unspeakable deviousness.
When Petiot was finally arrested, the French police hoped for answers.
