Detective Sergeant Daniel "Dan" Scott (John Hopkins) (series 7-8) is a lot cockier than his predecessor DS Troy; he is a Londoner who was not thrilled at being transferred from the Metropolitan Police Service to Midsomer, which he regards as the "sticks". His relationship with Tom was prickly at first; but it mellowed into a slightly awkward marriage of convenience, with Barnaby still disapproving of Scott's methods and Scott grudgingly starting to respect Barnaby.

Unlike Troy and Jones, Scott did not have a warm relationship with Barnaby, and he is Barnaby's shortest serving partner. In The Straw Woman, Scott develops a love interest who is brutally murdered. Scott's departure from the show was abrupt. In The House in the Woods, Barnaby describes Scott as having called him to say he was ill and thus unable to come to work. Barnaby invites Ben Jones to assist him on that case. After this incident, no more is heard from Scott, and Jones becomes the new deputy.
