Another batch of gripping murder mysteries is getting underway on ITV tonight as Endeavour returns for its eighth series, creating a conflict for fans of star Shaun Evans.
The actor is reprising his role as Endeavour Morse in three feature-length episodes, but on the other side viewers can also see him in the role of Chief Petty Officer Glover in BBC One's Vigil.
Fortunately, thanks to the magic of catch-up services, viewers can tune into both, meaning they won't have to miss out on a minute of either suspenseful drama.
The premiere focuses on a mystery surrounding Oxford Wanderers' player Jack Swift, who Morse is assigned to protect when a threat to his life is made, which could be connected to a devastating attack on the local college.
Once again, Roger Allam co-stars as Morse's partner Inspector Fred Thursday, with more details on all the cast and characters of Endeavour series eight listed below to help you refresh your memory.
Shaun Evans plays Detective Sergeant Endeavour Morse
Who is Endeavour Morse? Endeavour is the younger version of the iconic detective character played by John Thaw in the popular Inspector Morse series. He's highly intelligent but sometimes struggles to match the common touch or levels of tact displayed by his superior and mentor, DI Fred Thursday.
Morse also previously fell in love with Fred's daughter, Joan Thursday, who did not appear in series seven but is returning for the eighth series.
Speaking to RadioTimes.com about his character's love life, Shaun Evans said: "What we meet in the Inspector Morse series, or indeed if you pick up the books [by author Colin Dexter], there's a guy who never ends up getting married, and is kind of broken at the beginning, I think.
"So we have to have a bit of romance now in order to take us to that point. There has to be a sort of heartbreak thing. So I think just narratively there does need to be."
Where have I seen Shaun Evans before? The actor and director is known for previous roles in Teachers, Silk, Ashes to Ashes and The Scandalous Lady W. He's also directed episodes of Casualty and Endeavour, and directed the opening episode of season seven.
Roger Allam plays Detective Inspector Fred Thursday

In an interview with RadioTimes.com, Shaun Evans teased rising tensions between Morse and his boss this season: "It's more interesting I think when there is a bit of conflict there, you know."
