If you’ve ever found out something unexpected – something you never knew – about your parents or perhaps another relative, then you know how curious we can be about family members. In a way, finding out about a relative’s history gives us a piece of ourselves. And sometimes, those things we learn cast someone in a whole new light. In crime fiction, they can be an interesting part of a plot, too.

In Agatha Christie’s Five Little Pigs, Carla Lemarchant hires Hercule Poirot to find out the truth about her father’s murder. Sixteen years earlier, famous painter Amyas Crale (Carla’s father) was poisoned one afternoon. All the evidence pointed to his wife, Caroline, and she was duly arrested, tried, and convicted. Carla, though, is convinced that she was innocent. Poirot gets written accounts of the murder and the days leading up to it from the five people who were present at the time. From those accounts, and interviews with those people, he finds out who the killer really was. Those interviews and accounts also give Carla a chance to get to know her parents in ways that she hadn’t before. And she is glad of the chance to meet the people who were central in her parents’ lives.

In Graeme Macrae Burnet’s The Accident on the A-35, local chief of police Georges Gorki gets a new case. An attorney named Bertrand Barthelme has driven his car off the A-35 into a tree. Is it a case of accident? Was it suicide? It’s hard to tell just from the initial information, so Gorki decides to interview Barthalme’s widow, Lucette, and son, Raymond. Lucette claims that her husband shouldn’t have been on that road at all. He was supposed to be somewhere else at the time. She wants to know what really happened, so Gorki agrees to at least ask some questions. When Raymond learns of his father’s death, he decides he wants to learn more about him. The two were not close, and Raymond knows that he doesn’t really know the person his father was. So, in one major plot thread, he follows his father’s trail to find out what he was really like. And he makes some surprising findings.

And then there’s R.J. Harlick’s Death’s Golden Whisper. Meg Harris has recently left an abusive relationship, and is now living at Three Deer Point, in Outaouais, Western Québec. She inherited that property from her Great-Aunt Agatha, who lived there for many years, and developed a good relationship with the Migiskan people who live nearby.  So, when a company called CanacCold wants to mine nearby Whisper Island, Miskigan Band Chief Eric Odjik asks Meg’s help. He believes that Whisper Island may be part of the property willed to Meg. If that’s the case, she can deny the company the right to mine. Meg is only too happy to oblige, since she doesn’t want the company to have mining rights. So, she starts looking through Aunt Agatha’s things to see if she can find proof that the property is now hers. Then, there’s a disappearance. And a murder. Before long, Meg is drawn into a complex, dangerous case. As she finds out the truth, Meg also finds out a great deal about her great-aunt. And what she learns gives her a lot of insight into the area, Aunt Agatha, and the history of Three Deer Point.

It can be really tempting to want to find out things about parents, grandparents, and other relatives. Sometimes, we find out things we never imagined. Has that happened to you?
