ITV's Trigger Point is causing a lot of reaction on social media with many loving it - and some not so much.
Whilst others love seeing another tense drama back on TV, some people think the show is a little too slow with "not much happening."
Since Line of Duty finished last year and we finally found out who 'H' was, people have been waiting for another tense drama starring one of the most popular trios on TV.
And thanks to LoD's executive producer Jed Mercurio, we can see AC-12's Vicky McClure return to our screens knowing she won't disappoint.
In the second episode of the intense ITV drama, which returned on Sunday (January 30), Lana Washington - or Wash for short - was asked to give evidence in front of a committee about the recent bombings which saw her colleague and friend, Joel Nutkin, sadly die.
As they try to find out who is behind the awful killings, some people think that they have it all figured out after just two episodes.
With the funeral of Nutkin's having taken place, and not a dry eye in the room, people began to write their own suspect list.
Taking to Twitter to share their theories, one fan wrote: "So obvious who the bomber is. He was carrying the coffin."
Another said: "Might be a stupid theory but why do I think the man who dies last week faked his own death and is actually the bomber."
A third tweeted: "Currently suspect no 1: Karl "The Mechanic" = the bomber" whilst a fourth also said: "Its Carl Whos Bomber Calling It."
Do you think you know who the bomber is?
