After being hugely let down by the previous episode "Second Sight", which to me is one of the low-points of 'Midsomer Murders' and actually didn't feel like it at all, it was such a relief for "Hidden Depths" to epitomise what 'Midsomer Murders' is all about and what makes it so great when on form.
To me, "Hidden Depths" is the best episode of Season 8 and a strong contender for the best Barnaby and Scott episode. It is notable personally for three things. One, the chemistry between Barnaby and Scott is as delightful as one can hope. Always have enjoyed their spirited chemistry, and their scenes in the cellar in "Hidden Depths" will have fans relishing them with glee. John Nettles is superb as Barnaby and John Hopkins is a perfect contrast.
Secondly, the deaths in "Hidden Depths" are among the most deliciously elaborate, grisly and imaginative of the entire show, the second murder in particular is among the greatest 'Midsomer Murders' scenes. Thirdly, the final solution is one of the show's cleverest and most ingenious, one that is revealed later than most episodes before it and one that leaves one absolutely floored, plus it is very easy to follow and explained very clearly and neatly. Sure, the way the murderers are caught is somewhat too easy but not in a jarringly bad way.
Production values are top notch, with to die for scenery, the idyllic look of it contrasting very well with the story's darkness, and quaint and atmospheric photography. The music fits perfectly, and the theme tune one of the most memorable and instantly recognisable of the genre.
Meanwhile, the script is smart and thought-provoking with some nice quirky humour, a grimness and with characters that are colourful and eccentric. The story is very absorbing, never simplistic, never confusing and the maturity that 'Midsomer Murders' has when on form is more than evident here. All the acting is very good indeed.
Overall, brilliant episode and a perfect example of how to return miraculously to form after hitting rock-bottom. 10/10 Bethany Cox
