What you will be working on is underhanded, unfair, and damned un-English."
1887
The British Empire is in danger of collapse and teeters on the brink of war with the Kaiser Reich. Spies and saboteurs play at deadly games in the British shipyards as each side seeks naval superiority.
Ian Rollins is collateral damage in their shadow war. The "accident" and his grievous injuries are about to bring his naval career to an ignominious end. But with the aid of a former Pinkerton detective, a clandestine agent for the Admiralty, a brace of Serbian savants, and one, mostly sober valet, he might survive. If he can master the skills necessary to command the world's first fully operational combat submarine, the HMS Holland Ram, and protect the secrets of the Thunderbolt.
