London's "Gurdleston Trading House" is respected by all. With a firm hand he leads his commercial ship Gerdleston Sr. along the sea of ​ ​ everyday life. No wonder he was nicknamed by the people "Iron." The son does not lag behind the father. He has a tenacious mind and a sharp eye, at the card table with him - keep your ear open. Both follow the law and know how to play by the rules. But when the ship lurches and suddenly leaks - then watch out! No law has any power over them. The next volume of "Masters of Adventure" includes one of the first action-packed novels by Arthur Conan Doyle, written under the influence of Dickens and Haggard's African novels.
