Michael Strogoff, a 30-year-old native of Omsk, is a courier for Tsar Alexander II of Russia. The Tartar Khan (prince), Feofar Khan, incites a rebellion and separates the Russian Far Eastfrom the mainland, severing telegraph lines. Rebels encircle Irkutsk, where the local governor, a brother of the Tsar, is making a last stand. Strogoff is sent to Irkutsk to warn the governor about the traitor Ivan Ogareff, a former colonel, who was once demoted and exiled and now seeks revenge against the imperial family. He intends to gain the governor's trust and then betray him to the Tartar hordes.<br /><br />Critics, including Leonard S. Davidow, consider it one of Verne's best books. Davidow wrote, "Jules Verne has written no better book than this, in fact it is deservedly ranked as one of the most thrilling tales ever written." Unlike some of Verne's other novels, it is not science fiction, but a scientific phenomenon (Leidenfrost effect) is a plot device. <br /><br />The book has been adapted several times for films, television and cartoon series.
