Listen to an extract from Locked In by Kerry Wilkinson, read by Becky Hindley.
They think they are safe at home. Someone knows better.
The first in the Jessica Daniel series, Locked In is the number one bestselling crime thriller from Kerry Wilkinson.
When a body is found in a locked house, Detective Sergeant Jessica Daniel is left to not only find the killer but discover how they got in and out.
With little in the way of leads and a journalist that seems to know more about the case than she does, Jessica is already feeling the pressure - and that's before a second body shows up in identical circumstances to the first.
How can a murderer get to victims in seemingly impossible situations and what, if anything, links the bodies?
