Broken Oaths: An electric, chilling new crime thriller perfect for fans of Nadine Matheson

The brilliant third novel from the acclaimed author of THE COLOURS OF DEATH.

During a remote meeting, an official watches from Lisbon as his colleague, Inácio Machado, a Portuguese diplomat based in London's Portuguese embassy, dies of what looks to be a heart attack. When no one comes into the room to Inácio's aid, he tries frantically to contact the embassy to get immediate help. He tries and tries again, but no one picks up the phone and he's forced to call the British emergency services.

When local police arrive, they walk into a disturbing scene. Everyone inside the building is dead, all seemingly from the same cause.

Inspector Isabel Reis, a Gifted Inspector with Portugal's PolÍcia Judiciária has developed a reputation for closing sensitive cases involving powerful people. When the gravity of what has happened in Belgravia is revealed, she's called up to London to assist London Met's CID in the investigation.

The mystery takes another alarming turn when they realise that the embassy was harbouring an American-Portuguese military scientist who is unaccounted for.

One thing becomes clear very quickly: the deaths are murders, and Isabel faces capturing a killer more ruthless than she has ever seen before.
