The headmaster of a prestigious prep calls on Holmes for help in investigating the disappearance of the only son of his patron, a rich and powerful duke who seems more worried about staying out of the public eye than finding his ten year old heir. After he reluctantly agrees to allow Holmes to take on the case, The Great Detective investigates not only the missing boy, but a German teacher and the lone bicycle that have mysteriously vanished also.

The original story ended simply with the Duke telling the entire story to Holmes with the promise that Wilder would go and seek his fortune in Australia. This adaptations has a more dramatic ending with a chase led by Holmes, Watson and the Duke, in which Wilder keeps Lord Saltire hostage in an underground cave and falls to his death. See more »


Dr. Huxtable greets his pupils with the Latin "Salvete, Discipuli" ("Greetings, pupils") and clearly pronounces the "v". As an expert in Latin, he should know that it should be pronounced like a "w" in English, so the word should sound more like "salwete". See more »

A good entry in the series
10 June 2011 | by (United Kingdom) – See all my reviews

For as long as I can remember, I have been a big fan of Sherlock Holmes. The Priory School is a good, solid entry in the series. I do agree though the adaptation could have elaborated more on the glass case in the foyer clue, and there are moments when the pace feels sluggish. However, when it comes to the production values and music, The Priory School can't be faulted. The photography, sets, scenery and costumes are authentic and add to the atmosphere and once again the music is both beautiful and haunting. The story is one of the most interesting of the series and is told very well, the script is sophisticated and thoughtful-plus the episode has some of the funniest ever Sherlock Holmes moments involving Watson and food and a quite intense climatic scene- and John Madden's direction is appropriately skilled while not feeling too overdone or low-key. The acting is great as usual, Jeremy Brett is straightforward yet commanding and Edward Hardwicke is loyal and composed, while the support cast are all solid without standing out especially particularly. Overall, it is a good entry. 8/10 Bethany Cox
