Jake Palmer accepts an offer from a defense contractor to consult with the company on the death of an engineer assigned to the top-secret Perseus Project—the development of the navigation and targeting systems for an experimental Navy drone. Two days into the case, Palmer finds the defense contractor shot dead. What he discovers convinces him that both deaths are related to the project and that someone within the company is working with terrorists to seize control of the drone during a planned live-fire test in Afghanistan. With no hard evidence to support his theory, he is unable to persuade either the company or the Navy that an imminent threat exists. Concerned that he will disrupt the test, the company terminates Palmer’s contract and notifies the police. Pursued by the police and headed for engagement with a large, well-armed terrorist cell led by the company insider, Palmer is close to defeat when he receives help from the most unlikely person. With only hours to spare, they race to stop an attack half a world away.

Jake Palmer is attending a wedding in New York, and Fiona Collins has flown in from London to accompany him to the event. The night before the wedding a U.S. Homeland Security Investigations (HSI) special agent meets Palmer in the hotel bar and requests his help. He leaves Palmer a sealed envelope and tells him to review the contents, saying he will be in touch in a few days. Moments later, the agent is gunned down. Palmer decides to return the envelope to HSI but not until after he and Collins open it. Inside they find a cryptic note from the agent and information related to a counterfeit medicine case involving a drug manufactured by the company where Collins works. The next morning, they take the envelope to HSI’s New York office, ending Palmer’s involvement in the investigation, or so he thinks. Collins returns to London intent on finding more about the counterfeiting of one of their newest medicines. After an unexpected event changes Palmer’s perspective, he teams with the HSI special agent now in charge of the case. Together they pursue those behind a global counterfeit medicine and money-laundering operation. As the investigation unfolds, Palmer makes a startling discovery that raises his personal stake in the outcome and reveals the real reason the murdered HSI agent wanted him involved. With those closest to him now in danger and more patients dying from taking a medication that contains almost none of the life-saving ingredient, time is running out.

Former U.S. Navy SEAL, Jake Palmer, is searching for something to fill the void in his life, a void present since he left the Navy ten years earlier. Neither his previous work as a corporate attorney nor his string of short-term personal relationships filled the indefinable emptiness. When a former colleague at B&A Pharmaceuticals asks Palmer to investigate the deaths of a physician researcher and his nurse in a car crash in southwest England, he is reluctant but accepts the assignment. Palmer is teamed with Fiona Collins, a tenacious B&A research auditor. Collins believes Palmer’s role is to observe and assist her in auditing the deceased physician’s clinical research records, assistance she neither needs nor wants. While Palmer believes the sooner Collins completes her audit, the sooner he can commence his investigation into the deaths. They travel to a small town on the Cornish coast and follow a trail of evidence that leads them to London, where they become entangled in a web of deceit, ambition and murder. With their lives in imminent danger, Palmer must confront his demons and bring those responsible to justice, even if it means killing them.
