Input: Chief Superintendent Bright:  Perhaps you 'd care to explain just what it is you 're doing here .
DC Endeavour Morse: I think I know who killed Cartwright and Monkford , sir .
DI Fred Thursday: Think or know ?
DC Endeavour Morse: Know .
Chief Superintendent Bright: What 's this ? More threadbare legerdemain ?
DI Fred Thursday: Might as well hear him out sir .
Chief Superintendent Bright: But we 're about to charge Pamela Walters , are n't we ?
DC Endeavour Morse: Every Friday , Dr. Cartwright went to the East Cowley post office and had a postal order made out to the sum of 10 shillings . Every Monday , that order was cashed by Pamela Sloan .
Chief Superintendent Bright: Why would it matter if he was sending money to his sister - in - law ?
DC Endeavour Morse: Three years ago , Pamela Sloan attempted suicide . Frank Cartwright had been keeping an eye on her , since she moved to London . He found her in the nick of time . His own marriage failing , Cartwright understood Pamela 's desperation all too well . Two lonely people in a big city far from home , they looked to _ one _ another for companionship , and comfort .
DI Fred Thursday: He got her pregnant .
DC Endeavour Morse: I spoke to the National Registry first thing . There was a man called Gerald Walters who worked at ICI and he did die in a car crash but there was no whirlwind romance with Pamela Sloan . No marriage . For two years , they kept their affair secret . Pamela passed herself off as a young widow and collected Cartwright 's weekly postal order . Eventually , someone realised Dr. Cartwright was sending money to a woman who was not his wife . They fired a shot into the dark and hit the bull's - eye . The sender threatened to reveal what he knew to Cartwright 's wife and sought to turn it to their own advantage . Cartwright paid off the extortioner with a regular delivery of amphetamines .
Chief Superintendent Bright: And the Reverend Monkford ? How do you explain his involvement ?
DC Endeavour Morse: He came upon Dr. Cartwright 's killer at the scene . Unfortunately , the murderer also recognised the Reverend Monkford .
Chief Superintendent Bright: You might find this compelling , Thursday , but so far it seems to me nothing but surmise and rank flummery . If he knew who the killer was , why did n't he just come forward ?
DC Endeavour Morse: And explain what he was doing cycling to a public convenience miles from his parish at 10 o'clock on a Summer 's evening ?
Chief Superintendent Bright: You can prove none of it .
DC Endeavour Morse: Actually , sir , I believe I can .
