Elizabeth assesses the mental state of a KGB agent and the subsequent events require action from an FBI mole.
I enjoyed this one for the gender politics, its depiction of how intimate relationships are used to extract information and the development of several characters.
The plot isn't too complicated and is driven by another espionage related McGuffin, but you have to pay close attention to what is happening and being said, particularly in relation to the events involving the KGB agent we see at the start.
This opening sets the tone for what is to come, particularly around the use of sex as a weapon during espionage. There follows a number of scenes along this theme and they are done in a compelling way, with some focus on the aftermath, particularly the reaction of males to what the female characters have done. In fact the gender politics are are particularly apparent in this one, with the Russian female characters efficiently getting difficult jobs done whilst rejecting sympathy and support from males.
The above provides plenty of character development and insight into the main protagonists and their relationship, whilst also looking closer at some of the supporting characters. This has me intrigued about what will happen to them as the series goes on.
