"I suppose I'm in serious trouble now," stubbornly answered Walter, "but I won't take back what I said. The Juan Lopez has a lot of freight on board that doesn't belong there, and I intend to find out all about it."

Captain Brincker leaned forward in his chair, his strong, brown hands resting upon his knees, his keen eyes almost mirthful.
