Isabella Hartwell has crossed the Atlantic for reasons entirely unrelated to finding a titled husband. Society may assume she has come to England to buy herself a coronet, but Isabella wants something far more dangerous. She wants adventure.

Set in 1890s London, A Coveted Heiress is a Victorian historical mystery featuring Isabella Hartwell, a Gilded Age American heiress whose intelligence, independence, and sharp eye for detail make her a dangerous woman to underestimate.
London society is still deciding what to make of Isabella. She is wealthy, unmarried, American, and entirely too independent for comfort. When she attends an exclusive private event at Harrods, she expects spectacle, gossip, and perhaps another attempt by polite society to tell her what sort of woman she ought to be. She does not expect death.
At first, the tragedy appears to be a dreadful accident within the store’s glittering walls. But Isabella notices details others overlook and soon suspects that something far more deliberate has occurred.
Her investigation leads her through the drawing rooms, showrooms, and back corridors of Victorian London, where concealed debts, private bargains, bruised pride, and social ambition all hide beneath polished manners. In a world where reputation is currency, even respectability can become a motive for murder.
As suspicion spreads through high society, Isabella must discover who wanted the victim silenced before the killer decides that one impertinent American heiress has seen far too much.
