This is the 5th book in the series. Cormoran Strike is asked to help find Margot Bamborough who went missing in 1974. He is visiting his family in Cornwall and most of the book is about introducing Strike's family members. This book is a bit long but does further the relationship of Strike and Robin. I'm looking forward to the next installment to see where their relationship is going next. Robin herself is also juggling a messy divorce.
