When does Lockwood & Co. return?

The series is based on Jonathan Stroud's book series of the same name. It follows the plots of the first two books, The Screaming Staircase and The Whispering Skull. In an alternate version of present-day Britain, ghosts who are deadly to the touch have been rising from their graves for the past 50 years. Adults cannot sense the ghosts, but children can, so teenagers have been organised into licensed ghost-hunting agencies.
