Missing Through Time

Marcus and Ryan have teamed up again to find a missing person. Well, three of them, to be more exact. But it's the same person, taken from three different places in time. What would drive someone to take the same person multiple times? What is their end game? 

Two agents have joined the team. Adam, an agent for the World Bureau, has a secret. Will this agent stop him from doing what needs to be done? Will he get his head in the game and do what it takes to find Charles? Billie has temporarily joined the Bureau to help find her brother. With the new memories in tow, will she find the brother she became close to? Or will she lose herself in the chase?
