There’s potential here, and the writing (Pete McTighe) and the cast are strong (Rakie Ayola is also excellent as the intimidating lead detective, as is Eddie Marsan as Jack’s grieving dad), but the premise does seem far-fetched.

We must suspend disbelief for drama and I strongly suspect this will get better. I enjoyed the dialogue.

This is one of those dramas where the audience quickly has to make peace with the fact that every single character can and will make the worst possible decisions, or the plot would grind to a halt.
