The secret of the "Iron Lady"

1887. The young Zemsky doctor Ivan Inozemtsev, in order to improve the shaken mental health after the misadventures in the Bulovka estate, moves to Paris, but even there cannot get rid of the ghosts of the past and fears for the future. Despite the brilliant medical practice and lectures at the European University, Ivan Nestorovich understands that he cannot achieve a quiet and serene life in the French capital. One of his students is the grandson of Lessepse himself, a brilliant engineer and businessman, who is engaged in the project of the era - laying the Panama Canal. But the student himself contacts the anarchists and becomes the cause of the detonation of the explosive device. And only Inozemtsev understands that the fault is not a random oversight of a young chemist, but the Panama crisis and financial fraud around the Lesepse family
