In Code Green, the latest pulse-pounding installment in the Thomas Caine Thriller series, our battle-scarred protagonist finds himself thrust into a deadly chase that spans three continents. Caine must navigate the treacherous heights of Singapore's gleaming towers, survive the unforgiving jungles of Vietnam, and infiltrate the pristine facade of a Swiss castle—all while staying one step ahead of an army of killers who want him dead.

Now you can follow in Caine's footsteps with the final installment of this exclusive location report series. I hope you enjoy exploring the exciting and dangerous destinations that serve as the backdrop for Caine's most perilous mission yet…

As Caine’s mission leads him on a chase across Vietnam, Director Rebecca Freeling finds herself assigned to a CIA station house in Prague, the "City of a Hundred Spires.” Beneath the city’s fairy-tale facade lies a darker legacy: four decades of Communist rule beginning with the 1948 coup. During the Cold War, Prague became a Soviet satellite capital where 800 bunkers were built to shelter residents and propaganda sites like Vitkov Hill displayed the mummified body of Communist chairman Klement Gottwald. The city's struggle for freedom climaxed with the 1968 Prague Spring—crushed by Warsaw Pact tanks in Wenceslas Square—before ultimately triumphing in the peaceful Velvet Revolution of 1989, making Prague a testament to both architectural beauty and human resilience.

Deep beneath Vietnam's lush Phong Nha-Ke Bang National Park lies Hang Son Doong—literally "Mountain River Cave"—the world's most massive underground chamber. This limestone giant is so enormous that 15 Great Pyramids of Giza could fit inside it, and a Boeing 747 could fly through its largest passages. Stretching over 3 miles (5 km) long and reaching heights of 660 feet (200 m), Son Doong boasts a volume of 38.5 million cubic meters. The cave formed relatively recently in geological terms—just 2-3 million years ago—when two rivers carved through Asia's largest limestone massif, a 400-million-year-old rock formation. What makes Son Doong truly extraordinary isn't just its size, but its living ecosystems. Massive dolines in the cave ceiling allow sunlight to penetrate the depths, creating dense jungle environments that thrive in perpetual twilight. These underground forests exist alongside the cave's own weather system, where clouds form in the vast chambers and distinct microclimates create pockets of varying humidity, temperature, and light.
