Well, I loved it. Always record anything on a station with adverts, then can watch the drama and not the adverts. I did not think I would like the tache, but actually did - thought it suited him very well. This was obviously an introductory episode as he will be back in CID next week. Thursday had already said that if the brush case was handed in, then it would mean that it would cause every case he and his team had been involved in would be up for investigation. Although the owner of that brush case had been found guilty on planted evidence (which Thursday knew and concerned him), Morse finding the actual murder weapon vindicated the outcome of that trial - and rather than handing that in and starting all sort of problems for no good outcome, Morse put it back where he had found it. Prior to that, Thursday still thought that he had helped send an innocent man to the gallows.
In order for Morse to be transferred back to CID, it was implied to the Senior Officer that he was a member of a 'Lodge'. Such was the power of those secret societies back then. Morse life-long, hated and opposed such societies, and this probably had a result on his status in the police back then.
So no actual murder in this episode (except the one prior to the start for which the husband hand been hanged), Hit and Run.
Looking forward to rest of this series very much
