This episode deals with a sinister massacre in a Swedish fortified castle, the brutal execution of a man from Eisenberg and the mysteriously early death of Tutankhamun. An international team of experts successfully uncovers those questions that have remained unanswered for centuries: Why were dozens of inhabitants of a fortified castle murdered but no valuables stolen? Why was the man from Eisenberg executed so brutally? Did Tutankhamun die of an accident, an illness or was it murder after all?
