Mark Downer's Ghosts of the Past is a high-octane historical thriller that splices the dark secrets of World War II with a modern-day international treasure hunt. It’s a compelling read perfect for anyone who enjoys the blend of historical detail, globe-trotting adventure, and complex espionage, evoking the spirit of classic thrillers centered on Nazi loot.

The narrative is built on a fantastic hook: the final, cryptic crash of Major Max Hignite’s Luftwaffe transport in the Swiss Alps, which wasn't carrying military cargo, but a priceless collection of artwork stolen under the authority of Hermann Goering. This single event in 1945 casts a chilling, deadly shadow decades later.

In 2001, when protagonist Matt Ferguson inherits his great uncle Max’s mysterious legacy, the pace shifts into high gear. What begins as a simple discovery—a hidden safe, military gear, and a list of stolen art—quickly explodes into a life-or-death scenario. Ferguson, an ordinary American, is plunged into the underworld with the help of the assistant curator, Courtney Lewis. Their partnership is the emotional core of the novel, navigating ups and downs of trust as they are hunted by multiple parties.

Downer populates the world with compelling antagonists, from the wealthy and ruthless art collector Guillermo Rocca, who deploys his associate Juan to track every move, to the mysterious Bolivar. The stakes are underscored by a wave of violence, including break-ins and the attack on Dr. Karl, lending immediate credence to the book’s subtitle: this collection is, indeed, worth killing for.

The plot shines when Ferguson and Lewis arrive in the treacherous Swiss mountains. The author expertly balances the thrill of the treasure hunt—the discovery of the plane and the crates—with escalating danger. The tension builds to a breathless climax involving a multi-party shootout, highlighting the novel's fast-paced commitment to action.

Adding a strong layer of structure and investigative realism are Detective Toby Shutt and Interpol expert Charles Pernod. Their work to connect the dots between the domestic murders and the international art conspiracy provides a necessary anchor against the chaos of the treasure seekers, keeping the plot grounded even as the action flies.

The conclusion is satisfying, wrapping up the physical danger with a CIA takeover, yet preserving the personal mystery with Ferguson’s secret retention of the Gauguin painting. This final twist cements the complex character dynamics and leaves the protagonists—and the reader—with a rich blend of history saved and a personal fortune secured.

Ghosts of the Past is a meticulously plotted and engaging adventure. It successfully intertwines themes of historical intrigue, adventure, espionage, and character dynamics across different eras and continents. It is a captivating reading experience that promises to keep fans of wartime mystery and contemporary thrillers turning pages. A must-read for fans of authors like Steve Berry or Daniel Silva.
