The million-copy Sunday Times bestseller is back with a new thriller featuring D.I. Helen Grace.
"You have one hour to live."
Those are the only words on the phone call. Then they hang up. Surely, a prank? A mistake? A wrong number? Anything but the chilling truth... That someone is watching, waiting, working to take your life in one hour.
The job of finding out falls to DI Helen Grace: a woman with a track record in hunting killers. However, this is one case where the killer seems to always be one step ahead of the police and the victims.
With no motive, no leads, no clues - nothing but pure fear - an hour can last a lifetime...
