I must admit, I haven't read the book, so I went into Ordeal by Innocent quite innocently without any preconceptions. I was very impressed for sure, and had no idea who the murderer was until the very end. A stellar cast comprise this episode of Miss Marple. In particular there's Jane Seymour, along with Alison Steadman (who co-starred with Patrick Malahide in The Singing Detective). Reece Shearsmith also appears, and seven years later he would be a megastar in Inside No. 9.
