Of Thieves and Spies

Sara and Matthew weren't always spies. No, they used to be normal siblings, just living their boring old lives. Until that one night, 4 years ago. At the tender age of 12, they became orphans, and also more then that that awful night. They became thieves, stealing about $1,000,000 a month. But, after their most recent theft, when a spy agency contacts them. Will they join? And IF they do, what would they get. What gadgets would be enhanced?

P.S. Whenever the twins are on, just imagine the Mission Impossible theme going on. If you haven't heard it, The Piano Guys do an awesome version of it. Here's a link. https://www.youtube.com/watch?v=9p0BqUcQ7i0
