Doctor Who assistant spotting

Jenna Coleman has a new 4-part crime drama released last week:
   The Jetty
   Follows Det. Ember Manning as she must figure out how a fire
   at a vacation home is connected to a podcast journalist
   investigating a missing person's cold case and an illicit
   love triangle between a man in his 20s and two underage
   girls.

Some reviews are saying it is the best crime drama since "Broadchurch", which of course was another Doctor Who actor's show (David Tennant).
