The Making of Midsomer – a murderous exhibition

This summer… visit Midsomer, “the murder capital of Oxfordshire”


This exhibition traces Thame’s involvement as a major location in the series…

For 25 years the hapless Barnaby Detectives have rooted out death and destruction in the leafy lanes of Midsomer and its county town of Causton.

As we know – like the Mounties – the Barnabys always get their man – or woman – or ghost – but where is it all put together? who decides who “gets the chop” and how do they come up with the frankly ludicrous plots… Its amazing… its fantastic… its entertaining…. and you can see how Thame is involved for yourself at Thame Museum (or should that be Causton Museum???).

This unique, one off exhibition is open from 25th June until Saturday 1st October – and entrance is free

…Just don’t turn your back on the staff… or drink any tea they may offer you… or stand too long under the skylight…  After all – its an exhibition, not an episode!!!

Midsomer Murders, the popular ITV series, celebrates 25 years in 2022.
Thame is one of the most filmed locations in the fictional Midsomer County. The exhibition features many of the 23 Thame venues used as filming locations in the series, as well as some of the locations in nearby villages.

“I thought I knew some of the episodes of Midsomer Murders and about Thame’s involvement in them. But this exhibition at Thame Museum was a real surprise. It shows many episodes in this popular series which used Thame and surrounding villages as their locations. You will be amazed by how many episodes were filmed here in Thame. Many of the illustrations include cast members as they were originally seen. The photos are captioned and easy to read, with a quick guide to the storyline and episode number. You can test yourself: How many sergeants worked with DCI Barnaby and what were their names? Who were the pathologists who attended grisly murder scenes? In how many ways were victims killed?  It is a fascinating display, which is not only a trip down memory lane, but also puts Thame firmly on the (Midsomer) map.”     (Peter Sawyer)

“What a treat! So much information, so many great facts, such wonderful pictures – to say nothing of some of the props. Whether you’re a casual viewer of the odd show or a diehard fan, this exhibition is a delight.”   (Catherine Jones

“If you were wondering why Thame is famous, a visit to Thame Museum should answer your question. On show is a wonderful range of information charting the 25 years of Midsomer Murders and its links to Thame and neighbouring locations. The display includes photographs of the cast, location photographs, and even the original theremin featured in the theme tune. The exhibition was expertly put together by Helen Johns and Tony Long who organise the popular guided Midsomer tours of Thame.” (Jo Blenkinsop)

…. there is a feast now on offer at Thame Museum.  The exhibition has been designed with meticulous detail, using photographs and explanations depicting some of its many episodes. It illustrates the part Thame and our surrounding villages have played in providing the well- loved scenic backgrounds that have become an integral part of the show. This exhibition is well worth a look and could even be enjoyed by those who prefer watching Line of Duty or Sherwood rather than Midsomer Murders!”  (Erroll Bateman)
