The witness / Simon Kernick.

The gripping new race-against-time thriller by the best-selling author of Relentless, The Last 10 Seconds and The Final Minute. When Jane Wheeler witnesses her lover, Anil's murder, she suddenly finds herself the target of his killer. Rushed to an anonymous police safehouse after an attempt on her life, it soon becomes clear that the man she thought she knew was actually an MI5 informant with important information about an imminent terrorist attack. DI Ray Mason of Counter Terrorism Command is a man with a controversial past. Shunned by his colleagues and facing a civil prosecution for the unlawful killing of two terror suspects, he should be a pariah, but his effectiveness at getting results means he's now given the task of preventing the terror attack taking place somewhere on London's busy streets. But can DI Mason be entirely trusted, and does he know more about who's behind the terror attack than he's letting on? While Jane tries to piece together a description of the killer and provide the clues that will identify him and help stop the attack, she doesn't know that the killer has already found out where she is. And now he's coming...
