In the new episode 'Pylon', Morse finds the suitcase with the evidence that proves Thursday was right about the 1952 murder case. Yet at the end of the episode he hides it back in the church where he found it - why? Surely it would be safer to destroy it or bury it, as one day it could be found, eg if the organ was being repaired.
"why was Morse so cold to the Thursday daughter." Yeah, it feels like something was cut. There was that vague flashback where she says, "I can't keep doing this" which indicates that something happened or further words were exchanged after Morse asked about coffee in the previous episode.
I really enjoy this show but there are some mighty annoying plot holes.
