Lyndon Winslow, patriarch of an extremely rich family is dying. He calls all his family home even Florence who is the widow of his favorite son. They have been estranged and he wants to reconcile before he goes. On her way to the estate, Florence is hit head on by another car. It's a miracle she isn't killed and the other driver is.
The police investigate and they decide that it wasn't an accident; someone was trying to kill Florence. The detectives assigned to the case are a strange partnership. Dylan has just been promoted to detective while Carrie is about to retire. It will be Dylan's first case and Carrie's last.
It turns out that there are several candidates who might have wanted Florence dead. Her father had made enemies in Africa who killed him and threatened his family. Then there are the Winslows. Lyndon has just changed his will and included Florence in a big way, even putting her in charge of his trust. That doesn't sit well with the rest of the family. Can Carrie and Dylan discover who is coming for Florence before they manage to kill her?
Mark Mills is a British author whose earlier novels both won acclaim. In this one, he is deft at creating characters who seem real while also having their own issues. Dylan for one is about to come to the end of a long term relationship and balancing that with a job that he isn't sure he will be good at. Carrie is a former FBI investigator and has personal problems as well. The building of their relationship is interesting to watch as is Dylan's growing comfort with his job. I listened to this book and the narrator did a great job, being unobtrusive yet moving the story along. There are plenty of twists and turns and I'll look forward to more Mark Mills mysteries. This book is recommended for mystery readers.
