The hidden history of one of the world’s greatest inventors, a man who disrupted the status quo and then disappeared into thin air on the eve of World War I --- this book answers the hundred-year-old mystery of what really became of Rudolf Diesel.

September 29, 1913. The steamship Dresden is halfway between Belgium and England. On board is one of the most famous men in the world, Rudolf Diesel, whose new internal combustion engine is on the verge of revolutionizing global industry forever. But Diesel never arrives at his destination. He vanishes during the night, and headlines around the world wonder if it was an accident, suicide or murder.

After rising from an impoverished European childhood, Diesel had become a multi-millionaire with his powerful engine that does not require expensive petroleum-based fuel. In doing so, he became not only an international celebrity but also the enemy of two extremely powerful men: Kaiser Wilhelm II of Germany and John D. Rockefeller, the founder of Standard Oil and the richest man in the world.

The Kaiser wanted the engine to power a fleet of submarines that would finally allow him to challenge Great Britain’s Royal Navy. But Diesel had intended for his engine to be used for the betterment of the world.

Now, New York Times bestselling author Douglas Brunt reopens the case and provides an “absolutely riveting” (Chris Bohjalian, #1 New York Times bestselling author) new conclusion about Diesel’s fate. Brunt’s book is “equal parts Walter Isaacson and Sherlock Holmes,[and] yanks back the curtain on the greatest caper of the 20th century in this riveting history” (Jay Winik, New York Times bestselling author).
