There was no way to know that they existed - the group known as the Four Horsemen. They kept themselves hidden, stayed underground and covered their tracks by using one of their members to wipe any digital trace of them away. Dr Cressida Stiel. Pestilence. The Ghost of Princeton. In 2005 she was supposed to have died in a fire. A body left behind in the ash to cover her disappearance. Then in 2006 the FBI was hacked, almost no trace was left except for a message on Dr Spencer Reid's computer. A message of disjointed words, ending with 'help'. It wasn't until a few months later that he found out that it was Cressida. And that she wasn't a Horseman by choice. Six years after her faked death she runs to the FBI, turning herself in for questioning. But when you have lived years in fear and anxiety, it makes it difficult to trust others. Even when the team tries to sway her to help, the only person she can open up to is Reid. But what will happen after the three remaining Horsemen are caught? If they're ever caught? ||Spencer Reid Fan-Fic - Criminal Minds|| ||Takes place in seasons 6, 11-13|| ||Canon-typical violence, swearing|| ||Updated daily||
