Intelligence gathering by countries is an age old practice. The mere thought of spies conjures up thoughts of dark and mysterious men in trench coats rummaging through secret documents. But this is not always the case, and other methods are often used.
In modern times we have been alerted to intelligence gathering methods used by governments. It’s more often than not collected by digital means and electronic surveillance. Today’s technology however hasn’t always been with us, and in time gone by other methods had to be employed. One such unusual method for collecting sensitive information was deployed in NAZI Germany. The SD, a branch of the SS ran, of all things, a brothel for intelligence collection, known as Salon Kitty.
