They think they are safe at home. Someone knows better.
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?
