Perfect for you if...
- You love Victorian mysteries with a dash of romance, where the central couple's chemistry matters as much as solving the crime.
- You're drawn to protagonists with real flaws: Byron's fractured memory means he's unreliable, and that uncertainty keeps you guessing.
- You enjoy historical fiction set in 1888 London that plays with the darker underbelly beyond Whitechapel, including whispers of shadowy organisations.
Maybe not for you if...
- You need standalone mysteries that wrap up neatly; this is book one of a series and ends on threads meant to carry forward.
- You prefer fast-paced plotting; this builds atmosphere and character slowly, with investigation as a vehicle for deeper secrets.
- You want paranormal or fantasy elements; despite the gothic London setting, this is grounded historical mystery without the supernatural.
