Do you start at the beginning? As a mystery writer I am also a mystery reader. Many (most?) are series. I’m always looking for a new book, new writer, new series….. but that is where the dilemma starts. Do I read the current one? Or do I go back to the beginning and start there?I remember discovering Michael Connelly (apparently, I had been living on Mars in an isolated space station, that’s the only explanation for joining the party late). There were simply too many…. I jumped in at the current point and since then have dipped back in time whenever the mood strikes. I’ve liked picking up Harry Bosch and Micky Haller at various points in their lives, skipping forward and backward, knowing what was coming or learning what got them there.When I latched onto Sue Grafton and Kinsey Millhone I started with A is for Alibi and went from there (maybe it was the alphabet that made me feel obligated to march in lock step).As a writer I like to see how the characters have changed over time, how the writing had changed. Do the characters age a year between the annual publication dates (as do Louise Penny’s) or do they remain in an artificial era? PI Kinsey Millhone stays fixed in the 1970s whereas Martha Grimes’s Inspector Richard Jury works has moved forward in time, trusting that the reader will ignore the fact that he was a child in the Second World War (it works for me, but I was raised on Agatha Christie’s Hercule Poirot who was old during the First World War and kept on solving crimes well after the second war ended. Always old, never precisely older.).What makes series so successful? The ability to return to the comfort of a character who is an old friend? I think that’s what I look forward to the most.
