Over the past few months, Kari and Jade of Boston's Madison Investigations Agency had handled several local investigations that just happened to overlap with FBI and CIA operations. Still, they were surprised when they were approached by the U.S. government trying to acquire them as new agents for the CIA.
The Madison twin sisters had spent almost ten years with the Boston DEA Police Department before they decided to strike out on their own and opened Madison Investigations Agency at 35 Beacon Street. After the grueling Boston Serial Killer case, in which they had worked side by side with the FBI, they were surprised to be approached by the US government. The CIA had somehow gotten involved in their case when some of the leads took them to Mexico where Kari and Jade met CIA Agents Stan Chambers and Ronnie Statin for the first time. A few weeks later, they were approached with job offers.
Thinking about the offers, the sister PI's decided they could use a new challenge and the prospect of working to help their country versus following cheating spouses and chasing down missing person cases would be rewarding. They reluctantly convinced the CIA Brass to let them keep their Private Investigation Firm open while they had two other investigators run it for them and act as a CIA informants. Promising, of course, to keep all of their CIA undercover assignments strictly confidential.
Their first assignment was a joint venture with the Russian FSB and SVR Agencies to investigate and stop multiple terrorist threats in Moscow. Being their first foreign assignment, they were assigned to work in two teams with CIA Agents Stan and Ronnie, along with Russian Agents Boris Petrov and Ivan Smirnoff. They were in for a very bumpy ride!
