Amy Bryne, MI-5 archivist and analyst - a glorified librarian really. She's perfectly ordinary, a bit above average intelligence, and just interesting enough to gain the attention of Mycroft Holmes. With information going missing and the release of the names of MI-5 and 6 operatives, she may have to learn to be something just a bit more than ordinary. She has three hours. The clock is ticking. And Mycroft's heart isn't going to be beating much longer.
