In a town famous for healing waters, one sip could mean murder.

Mineral Wells, Texas, 1924

Lady Anne Worthington, an English countess and brilliant inventor, has been shipped to America to find a wealthy oilman husband. But the independent Lady Anne has other plans?and they don't include marriage. While on a U.S. tour to showcase her Sherlock Holmes-themed murder machine, she's poised to make quite the splash.

When the tour's promoter, washed-up actor Baxter Knight, dies after drinking the famed mineral water, Lady Anne suspects foul play. As small-town secrets bubble to the surface, nobody at the peaceful spa retreat is above suspicion.

With the stubborn local sheriff targeting the wrong suspect, Lady Anne teams up with a handsome new-in-town Texas Ranger to unravel a mystery buried deeper than the healing wells.

Will Lady Anne's search for justice bring her closer to a found family? Or will the killer leave her more isolated than ever?
