1920. It all began with the murder of the English sailor Jeremiah Perkins in Havoysund and the mysterious packet he sent to Lady Elisabeth Faraday before he died. Or perhaps the story begins before, when some strange relics were discovered that led to Professor Ulises Zarco, director of the geographic society SIGMA, to embark on an incredible adventure on board the Saint Michel. Both Zarco and his assistant have ranged over the world facing all kinds of dangers, just like captain Verne and his crew or the two English ladies who have solicited their help; but none of them are prepared to face the terrifying mystery that surrounds Bowen’s Island, beyond the Arctic Circle.
