In January 1758, having returned to London, Grey meets General Sir George Stanley, his mother's fiancé, and, formally, Percy Wainwright, Stanley's stepson from his second marriage. Grey and Wainwright become romantically involved, despite Grey's continued feelings for Jamie Fraser. Wainwright also joins the 46th Regiment, which is assigned to fight under Duke Ferdinand of Brunswick in the Rhine Valley during 1758. While in the Rhine Valley, Wainwright is caught in flagrante delicto with another man, by Grey and two other soldiers. In the aftermath, the man is then discreetly shot by his commanding officer, Captain von Namtzen, while Wainwright is arrested and sent back to London to await a court-martial. Before returning to London, Grey fights at the Battle of Crefeld on 23 June 1758, where he takes charge of a gun crew that has lost its commanding officer. During the battle, the cannon blows up, severely injuring Grey. Once back in London and on the mend, Grey arranges to have Wainwright escape from prison and flee to Ireland. He also discovers the identity of his father's murderer, and clears his family's once-tarnished name. It is during the course of this novel that Geneva Dunsany gives birth to a son, William Ransom, shortly before both she and her husband die.
