Ken Follett - Alattunk az ocean (2021)

Everyone just called the plane Clipper. It was officially called Boeing B-314.

After the outbreak of the Second World War, the Pan American airline entrusted the Boeing company with the production of an airplane capable of flying across the Atlantic Ocean, a passenger plane whose passengers will receive all the luxuries during their journey. Unsurprisingly, this luxury did not come cheap. Passengers were limited to members of royal families, movie stars, presidents and CEOs of large international companies, and heads of state of smaller countries.

Except maybe Tom Luther. He was rich as a rich man, but he worked hard for his wealth, so he was not in the habit of wasting it on luxuries. A very powerful man asked him to perform a dangerous task...

He won't get paid for doing his job, but the very powerful man will owe him a favor worth more than any money.
