Returning home from a New Year’s gathering in 1823, Robert Archer, formerly of the 26th Rifles, stumbles upon a trio of were-beasts (shape-shifters) who can’t be up to much good. Only the aid of the lady night-slayer lets Robert reach home intact.
When the next morning, the body of a murdered man is found near the place Robert encountered the weres, he reasons they’ve hunted and killed the unfortunate gentleman.
To his shock, the were-beasts, who dress in the finest Bond Street attire, seek out Robert to enlist his help to prove their innocence. Robert embarks on the dangerous quest, which mires him in the secrets of the weres and teaches him new lessons about trust and treachery.
