Miss Scarlet

After Eliza Scarlet's father dies, she takes over his detective agency, against the wishes of everyone around her, including Inspector Wellington (aka the Duke). Can she prove to herself that she has got what it takes to be a detective?

As London's only female detective, Eliza is struggling to get work. Desperate for money, she takes a seemingly impossible case; proving the innocence of a man who has pleaded guilty to murder.

Eliza is hired by Duke to infiltrate one potentially disruptive group. Eliza is delighted in his faith in her abilities. She is less delighted when she learns she will be spying on a women's suffrage group campaigning for the vote.

When a ‘Death Photographer’ receives threatening messages from beyond the grave, Eliza must also reflect on her own late father.

The final entry in Henry Scarlet's casebook takes Eliza to an abandoned prison on the outskirts of London. She and Duke investigate what seems like an empty building, but they soon discover that it is the hideout for a criminal gang.

Eliza is determined to discover who murdered her father and why. Moses is the prime suspect, but the real murderer may be someone who has been under Duke's nose the entire time.
