Series finales are notorious for killing off beloved characters or leaving someone’s life hanging in the balance, with a “to be continued” flagged for next year. In Endeavour ’s gripping season five finale, who will make it out alive? Featuring beautifully drawn and believable characters, anyone’s exit would be a teary affair. Tonight, Morse (Shaun Evans) goes undercover to investigate the disappearance of a teacher at a public school. With news that Cowley Station is due to close, Thursday (Roger Allam) is determined to solve the murders linked to Eddie Nero. No matter what transpires, season six is on its way.
