Violet Milton is working as a shorthand typist in New York when she inherits the largest paper mill in Europe. Feisty Violet decides to take over the running of the English company, and is warned by a well meaning employee that something mysterious and dangerous is being manufactured in secret in a hidden part of the factory.
This story was written in the 1920s when political correctness in fiction was not even on the horizon, and a villain was often physically disabled or disfigured to make him or her appear more villainous. Note that the physical descriptions of the characters are from the original book. This is an old fashioned story of murder, industrial mayhem, and a weapon of mass destruction -- with a touch of romance.
