Sevilla, 1502: When Thomas Berrington is sent to southern Spain by King Henry, he expects diplomacy—but instead finds danger, deceit, and death. Can Thomas uncover a killer’s identity before he becomes the next victim?

Accompanied by his trusted companion, the eunuch Jorge, Thomas’s mission is to aid marriage negotiations between Catherine of Aragon and Prince Harry. But their task turns deadly when one of Queen Isabel’s closest advisors is murdered. Amid Sevilla’s bustling trade in exotic flora, fauna, and riches from the New World, Thomas confronts a maze of suspects whose motives are buried beneath secrets as deep as the ocean.

To navigate this perilous web, Thomas enlists the help of Rosa, a resourceful herbalist, and Baracoa, a freed Native American whose intimate knowledge of the New World proves invaluable. Together, they uncover a trail of corruption and greed, discovering how seeds brought from distant shores have taken root in Spanish hearts, poisoning even the noblest intentions.

As Thomas and Jorge close in on the murderer, they realise the stakes are higher than they imagined. They must race against time to thwart a conspiracy threatening not only the marriage alliance but the very future of Spain. Yet, with every revelation, the question remains—are they already too late?

A Surfeit of Grief is the latest thrilling entry in the Thomas Berrington Historical Mystery series, weaving danger, deception, and betrayal through a world poised on the brink of transformation.
