"The Argus Institute Personnel"

Copyright 1917
10th story included in the collection .
This story relates the trouble that a good spy encounters when having been in the business too long; the practice of spying becomes ingrained so that the operative invariably begins to spy on his/her own government and soon learns too much to be allowed to live. That is something that Olga von Marx starts to experience but not as much as a colleague.
