The Silken Wallet

Published in Pearson's Magazine, July 1913.
Angered by American immigration policies after the end of the Japanese-Russian War which allowed far more Russians to immigrate than Japan, tensions were high between Japan and the US. At particular worry was something happening to the soon to be finished Panama Canal. Grantham Waldron, among others, was tasked to learning as much as possible about Japanese intentions. He will immediately come into conflict with Maria Antoni, the "most celebrated spy that had ever worked for hire".
