Ooh! You're supposed to put a spoiler alert! Some people get quite upset when the ending is given away! 😁

You are a naughty boy John!!! Giving away story lines. Tut, tut!

Really not struck on the wife's voice..a bit too BBC English.

*By end of episode 1, there'd been a number of clues, or red herrings!* - blackmail, it's usually someone you know - the daughter's *boyfriend* is writing a story about law, he's a lawyer, I think. He may be the red herring, or maybe not! - *the wife* could be testing him! He may have had other dalliance that she's seen signs of, but she hasn't been able to pin him down! You're very clever, she has implied he's cunning: that he'd be two steps ahead of any investigation she might do into a real-life love affair. When he set up the company, going out on his own, he'd told her there'd be lots of travel involved! In Episode One, or possibly beginning of next one, she has said she had been expecting him to be unfaithful, and had in her own way accepted it as part of marriage. We don't yet know what her career is, I skipped a bit, maybe it was said already, or that becomes part of a future plot point. - protagonist has history of someone who kept themselves hidden or secret giving him a hard time; happened when he was young, playing sports, and someone he had bested on the field was getting their own back by causing problems: a revenge motive: with ENVY suggested. One suspect, unlikely possibly, but unlikely things happen in mystery fiction (as in life!) is the next-door *neighbour* who is clearly henpecked, and possibly he's envious of the happy marriage. The fact that neighbour suggests *his detective* embroil neighbour further in plot! Nice array of suspects and red herrings. . By beginning of Episode 3, am wondering if it's the man himself! Seems improbable. He says he's fighting for his marriage. But wife suggests he's cunning. We are not seeing any psychological complexities in dialogue, no gaslighting for example, so relying on details given in plot.

Thought it was amazing how she shows suspicion but in a very unaccented manner, very low key, just posing questions. If she'd been more emotional, it might have got in way of story, imo. Her name is Sandra Clark, they said at end. Not much about her online. Think she's been in *Eastenders*
