The first episode of the new series of Endeavour with Shaun Evans as Endeavour Morse and Roger Allam as Fred Thursday starts with the death of a young woman with a heart condition.
In ‘Girl’, Margaret Bell is found dead. Endeavour suspects that the

death may not be down to natural causes, suspicions that bring the detective into conflict with his superiors, in particular with new character Chief Superintendent Bright. He refuses to believe Morse’s theories and thinks Thursday has promoted him above his station.
CrimeTimePreview released this information together with the first official picture of the new series.
