Heather Petty Books in Order

Teenagers Sherlock Holmes and James Moriarty investigate a murder in a London park. Their growing attraction complicates the partnership, especially as Mori discovers connections between the killings, her late mother, and secrets within her own troubled family.

With her abusive father imprisoned, Mori hopes for safety but receives threatening letters. Anonymous accusations then implicate her in the Regent’s Park murders, leaving her and Lock to identify whoever is trying to destroy her life.

Held captive in the English countryside with her brothers used as leverage, Mori plots her escape. Returning to London brings a chance for revenge against her father and his allies, while Lock struggles to stop her increasingly dangerous campaign.
