I was stunned by the "whodunit" ending -- it came out of left field and yet it was all there in front of me and I had missed it. I read a lot of mysteries and can often guess the culprit but although there was a little bit that I was right about, most of it I just missed.
The plot is complex but not so complex that you can't follow it, in part because there are a limited number of characters. Two murders of well-heeled women take place in the same area (neighboring towns in England) on the same night -- and the two victims (who don't know each other) have been talking on the phone that night. Police Detective Inspector Lloyd is heading up the investigation of the first murder discovered -- a talented artist who has married for money -- and his live-in girlfriend Judy Hill, who has recently transferred to a new jurisdiction because of their relationship, is heading up the other murder -- a woman with a streetwalking past who is married to a man known to have a history of very shady business activities.
Did the same person kill them both? How are the killings related (if they are)? What was the motive or motives? This is a cozy in the sense that the list of suspects is reasonably short (spouses, boyfriends, etc.) and it's a question of puzzling out what happened that night -- talking to witnesses, recreating the night, etc.
This is my first by this British author but I intend to read more.
