NEW science fiction action movie from the bestselling author of “The Gunsmith. Rifles for Peter the Great." A brilliant inventor changes the past by establishing mass production of rifled weapons and sea mines a century and a half ahead of schedule. It was King Charles XII who was shot with his sniper rifle. His steam destroyers will send the Swedish fleet to the bottom, hastening the victorious end of the Northern War. But in the new version of history, it is no longer enough for Peter the Great to conquer the Baltic states and “cut a window to Europe” - rearmed Russia is ready to challenge the Lady of the Seas! And the gunsmith will have to become an “undercover” intelligence officer and a grandmaster of “the game on the world chessboard” in order to plant a mine under the British Empire!
