A London Underground conductor named Sally Hazard witnesses a “one under” on her shift–she watches in horror as a man is pushed off of the underground station edge and goes under her train, unable to stop it in time. But when Sally reports the murder to her supervisors, she’s told that the man wasn’t pushed, he just fell–and that the accident was caught on tape. Knowing she saw a murder and not an accident, Sally’s investigation leads her to Agent Ed Tarn, MI-6. Together, Sally and Ed will uncover the secrets of the underground, go toe-to-toe with alien assassins and discover an intergalactic consipracy.
