Well DC Steve Bradshaw has something to do in this episode but he still feels like a background player in this series.
The Tower still looks like elements of other police shows put together. This episode confirms it with addings bits of Line of Duty.
Matthew Brannon puts a video online as to how he has been picked on by the police. He specifically blames PC Lizzie Adama. However it also looks like someone inside the police department is helping Brannon. Maybe a reason why he has remained elusive.
As for the search for Tania Mills. DS Sarah Collins manages to convince her bosses to authorise a search at the local park. Only there is no body where they do the dig. Still Collins is not finished, she suspects music teacher Adrian Stephenson has buried her somewhere there.
Altogether watchable, with some tension. It is just too vanilla in its writing. Nothing too original.
