Status Updates From El secreto de Agatha

I'm enjoying this book, but I must say I know a lot of Agatha's biography through Lucy Worsley and David Suchet documentaries. I wonder if anyone reading with knowing little to nothing about Agatha would "understand " the book. Meaning references are made or certain situations and I know the backstory. The author gives a tiny bit but without my extensive background knowledge I wonder if I'd continue reading.
