Connor Simpson is a character appearing in the episode Death in Chorus of the ITV crime drama Midsomer Murders.
Simpson is a released art forger, after having served three of a five year sentence and changed his surname from Pierson. Simpson retired to Midsomer Worthy, where he painted scenic views, had an affair with Ellen Barker, party entertainer and spouse of choir conductor Laurence Barker, participated in the local church's choir program, and racked up serious debts from gambling. Simpson met Giles Armitage and Leo Clarke at the rings and devised a plan utilizing Simpson's forgery skills to get their debts paid off. Giles would sell paintings from his estate, Simpson would make the forgeries over a matter of weeks, Clarke would find the paying customers.
However, Simpson was ready to keep the paintings himself to sell, as he wanted to leave the village with Ellen. Clarke scared him by tacking a pig's heart to a poison pen note, but Simpson still wouldn't budge, even after fainting at choir practice he attended with Clarke. When Clarke personally pleaded to Simpson and said he'd turn him in, Simpson just laughed about how they'd all go to jail. Clarke bludgeoned Simpson in his head with a fire iron and tried to look for the stolen Bach painting Simpson was to fence, but Stephen Latimer was about to come in, so Clarke left him to find the dead man.
Clarke and Giles also resorted to killing Sam Judd, Giles' fired estate manager who had photos of the men during their meetings as payback, and falsely imprisoning, drugging, and nearly drowning Giles' wife Carolyn as a witness as well. Giles was arrested during the latter, and Clarke was caught when he nearly tried to make off with the painting, which he nearly burned as a threat if he didn't get away clean.
