S3E20 - 'A Stitch in Time' - Two hits in a season of mostly strike-outs.

The episode opens with Watson on her way to met Gregson's daughter Hannah to discuss a case.
Holmes suggests to Watson to stay away for a few hours while he re-captures his escaped bees.

Holmes is next called to the scene of a murdered Internet advocate. The victim was found murdered in his car at a railroad crossing.
A hope for accident with a train would have been to cover up the murder. The train wreck did not happen.

The victim was known for trying to debunk scams of various kinds. One of the advocates latest targets had been a ruined financier.  This financier had been trying to purchase a home from a women who's daughter had called the advocate to prove to her mother that her house was not haunted. The advocate was convinced the ruined financier was the source of the ghostly 'happenings'.
Holmes deduces that the sounds or other ghostly 'happenings' the women hard were not a ghost but rather sound and vibration caused by digging at a neighboring home.
It is then determined that the advocate had been murdered at the neighboring home when he discovered a man digging in the basement trying to get to a trans-Atlantic cable.  (Considering the size of the hole, the lack of machinery, and the lack of disruption in the neighbors basement, unless the houses were connected, the lady would not have heard or felt much.)

Once again neither plots Holmes or Watson are involved in are done as good as they good be. But both, however, did hold several good Canonical references and once again timely and topical.

The opening with the bee's is obviously, once again, a nod to Sherlock Holmes' hobby later in life of bee keeping.

We get the return of an 'irregular'.

We then get a Canonical nod when Hannah mentions that neither Watson nor Holmes cares whether or not they get credit in the resolution of cases.

Another Canonical reference found in the Hannah story line is the suggestion the local police lack imagination and vision when on a case. (Is Hannah's middle name Lestrade?)(Do either of these describe Hannah:  "the best of a bad lot ... both quick and energetic, but conventional — shockingly so." or ". . . had almost no skill at actual crime-solving, his (her) tenacity and determination are what brought him (her) to the highest ranks in the official police force.") 

Another one is when Holmes is at the morgue and he talks about the debunking of spiritual frauds (among other things). Spirits need not apply. In HOUN Sherlock comments on criminals for another world are out of his realm of deduction.
It is also a nod to the unpopular publicity Doyle received for his interest in the spirit world and how some tried to debunk his beliefs in it.

The tunnel between the two houses were similar to REDH. But a better connection could have been made if the old lady had been gotten out of the house under some pretense. (And it would have made for a better story. Tell her she won a free cruise or something.)

I found Miller's Holmes once again closer Canonically than most episodes. At times he was rather manic in his pursuit of information and how he went about the investigation. At others rather subdued and reflective.
His observations of Hannah were well done.

Although Watson is still acting more detective than side-kick, most of her deductions the last couple of weeks have been reserved for the cases she has individually taken on, leaving Holmes the chief detective of the 'A' plots in both episodes.

As Sherlockians we will probably never be satisfied with many of the plots in a show like 'Elementary'. There of course will be some stand outs, but for the most part we will continue to hope for plots that are more or less modern adaptations of the Canon where we won't have to search to hard for Sherlock Holmes. And if that doesn't happen, we at least want a show with strong Canonical references.

And for the most part, in this episode,  Holmes' annoying habits were once again played down.

I found this episode fun to watch and again liked Miller's Holmes.
So I can therefore fairly give it;
