‘Duplicate Keys‘ is a who done it character study of friends, with a bit of thriller at the end. While I enjoyed the story, motivations didn‘t seem very realistic, nor did the (mostly unexplored) music scene. I did appreciate descriptions of early 80‘s life in NYC, including dinner prices and salaries ($30 take out dinner for five is expensive, a 17,000 salary is enough to live alone in a nice apartment). This was probably a 3-3.5 star for me.
