Meet Rachel Proulx, an FBI agent with a tough mission in a thrilling short story from Olen Steinhauer, leading up to his novel, The Middleman (August 2018).

Rachel has been researching underground leftwing movements on the West Coast, but she knows she won't get any real info unless she goes undercover. So she heads out to San Francisco, moving into a tiny studio, and puts her ear to the ground. But what happens when she joins a group of them for a night party in Sonoma gets her more than she bargained for - and may even get her killed.
