The Ruby in the Smoke

Sally Lockhart's father was an unconventional man who preferred to teach his daughter how to run a business and shoot straight from a pistol rather than school her in the social graces expected of a young lady.

When he dies suddenly and unexpectedly on a voyage to the Far East, Sally receives a mysterious letter containing a strange warning — one that leads to yet another unexpected death.

Soon Sally finds herself at the heart of a deep and dangerous mystery — one she is determined to solve at all costs.
