Captain Gregson takes centre stage in this week’s Elementary…

The episode opens with quite a frightening murder. Two people are shot in their home and the contents of their safe stolen. Sherlock sees the connection between the case and another from the nineties, a case that Captain Gregson solved.

Gregson doesn’t listen to Sherlock’s theories that a copycat killer might be on the loose or that the original killer might be still out there and a innocent man is serving time. It’s a bit unbelievable that the detectives still doubt Sherlock even though he’s usually right or close enough. This is a personal case for Gregson as it was a career defining moment for him  when he put the perpetrator behind bars. His old partner Terry D’Amico joins them in the investigation after it becomes more clear that maybe a copycat is at work.

Holmes and Gregson visit Wade Crewes the man who is believed to have carried out the crimes in 1999 and we are made to think that maybe he is innocent. Sherlock also starts to doubt Gregson and takes no pleasure in finding out that a piece of evidence may have been planted by him at a crime scene that would later help convict him. Of course Gregson wasn’t responsible but it was his former partner Terry. Sherlock thinks he’s found the real killer who may have slipped the net before when questioned in 1999. He’s recently been relased from prison and seems to be the likey culprit. But despite finding the murder weapon in his apartment Sherlock deduces that he is blind in one eye making it unlikely he could shoot so well, proven when Sherlock throws an orange at him.

Someone is working with Crewes on the outside to set someone else up and get him freed and Sherlock finds his helper when watching the news and noticing how well read he is quoting from famous literary works. Sherlock thinks that someone in the prison library is the one helping him. Who works there, but the son of a woman Crewes was having an affair and had a secret child with, who we saw on screen for all of two minutes earlier.

Just like the secretary and the janitor in previous episodes they’ve barely had any screen time and for them to be revealed as the killer is just a flat conclusion. Watson didn’t get involved in this weeks case much as she was busy digging into Sherlock’s past and finds letters from Irene Adler. Let’s hope when she inevitably arrives she’ll be as fun as Lara Pulver’s Irene from BBC’s Sherlock. The episode gave more to Gregson to do and it was nice to see him take centre stage rather than just introducing this weeks dead bodies. Elementary is getting into the bad habit of giving quite interesting cases a poor resolution. I’m beginning to loose interest but I’ll stick with it in the hope that it will improve.
