Sophie Zagarovna's Secret
William Le Queux
Contained first in the collection and then in the collection .
Anton Prehznev is assigned the task of shadowing and monitoring a Russian recently arrived in England, certain that while he was supposedly representing a Moscow merchant, he was actually an agent of the Secret Police. While doing so, he was surprised to be approached by a lovely high class lady who passes him a note in secret. She is Sophie Zagarovna, "one of the most daring of the Zurich Nihilists". In question then is why she is in London and what help does she need from Prehznev.
