Crombie, D Fans of P. D. James, Peter Robinson, and Elizabeth George will enjoy this long-running mystery series featuring Scotland Yard detectives Duncan Kincaid and Gemma James. One of the most enjoyable things about this series is the character development. The relationship between Duncan and Gemma anchors the series, having progressed over time from professional and straightforward to personal and complicated. It’s not necessary to read the entries in the series in order, but it helps to fully appreciate how the relationship between Duncan and Gemma has developed over the years and to better understand some of the background, which is referred to in later entries. The first entry in the series is A Share in Death. ***
