Eighteen year old Emma has just finished school and gets a job as an office gofer at the Rosemond Valley Post. The editor-in-chief asks her to do some research on a famous daughter of Rosemond Valley: the Hollywood actress Kit Grace, who is visiting the town and is staying in the Grand Hotel. Emma discovers soon that Kit Grace isn't her real name, and that a relative of her is still living in Rosemond Valley.

She also learns about a unsolved jewel robbery that happened some twenty years ago. Jack Griffin, a former janitor of the Rosemond Valley Museum, was convicted for the robbery, but the jewels were never found. The arresting officer Captain Parker disappeared shortly after the trial. Emma becomes involved when a stranger is leaving notes about the robbery.

During her quest Emma will discover the secret past of Kit Grace and she will wonder if Kit is somehow connected to the robbery. But there are various other suspects, including her co-workers at the newspaper, and Emma has to reveal a lot of secrets before she is able to solve the mystery.
