Adventuring from England to Russia in the 1570's turns up some fairly bizarre touches and Sir Guy Spangler's commission to rescue the valuable cargo of the Companie Merchant Adventurers develops into a dangerous gamble. For Ivan IV (The Terrible) has taken a fancy to Lady Mary Hastings, from her portrait, and Sir Guy, to insure the safety of his venture, gets Ellen from prison to pass as Lady Mary's ""twin"" and bride for the Tsar. Representatives of the Companie go with them to protect their interests and, after hazards at sea, on land and en route to the Kremlin, Guy is pursued by spies, by the terrors of the Metropolitane and of the Equerry, and eventually becomes enmeshed in delicate dealings with the Tsar. His men, Pistol and Affable Jones, the young whore, Charity, the deformed Pojo, and the Tsar's loyal barbarians add to the excitement until Ellen is rescued -- for Guy's arms alone. The Russian dressing here may give this a new look but the basic line of historical fiction remains the same. Perhaps the exploits are more exclamatory!
