| Sarah | Welcome to Clued in Mystery. I’m Sarah. |
| Brook | And I’m Brook, and we both love mystery. |
| Sarah | Hi, Brook. |
| Brook | Hi, Sarah. Well, we both have siblings, and so I think today is going to be an interesting conversation about siblings in mystery. |
| Sarah | I’m looking forward to this. |
| Brook | Few relationships carry as much emotional weight or potential for tension as that between siblings. They share the same memories, the same wounds, and often the same secrets. |
| Brook | When this relationship is built into fictional crime stories, it packs a punch. Whether siblings are protecting one another by covering up a crime, or acting as rivals on opposite sides of an investigation, they make for some of the most compelling characters in mystery and thriller fiction. |
| Brook | As Megan Abbott pointed out when she joined the show, brothers and sisters have their own shorthand, a glance, a word, and they can cut right to the heart of each other. That deep understanding can build incredible loyalty, but it can also create danger, because when doing the right thing means betraying your sister or brother, the moral balance becomes very hard to strike, and irresistible to watch unfold. |
| Brook | Writers have recognized this power for generations. Think of “The Fall of the House of Usher”, the original sibling thriller, or We Have Always Lived in the Castle by Shirley Jackson. These are both eerie explorations of secrets, shared trauma, and devotion pushed to the edge. And while these stories border on horror, there’s a clear connection to contemporary mystery thrillers. |
| Brook | Whether fictional siblings are working together as an unbreakable team or torn apart as adversaries, their stories get close to home for anyone who has a sibling. They give us the opportunity to consider our own family bonds, rivalries, and shared stories, and how we might feel in the character’s shoes. |
| Brook | So we’ll explore why sibling dynamics continue to be one of the genre’s most enduring ingredients and mention some of the stories that come to mind for us in this category. |
| Sarah | What a great introduction, Brook. And I think you’re absolutely right that that relationship between siblings can be so fraught with tension, right? The wrongs that you feel you get from a sibling are 10 times worse than those that you could get from anybody else. |
| Brook | Yeah, exactly. Or that sense of responsibility and loyalty. You know, I’m a big sister. And so like, don’t mess with my little sister, right? |
| Brook | That feeling that you get is so strong and and almost the way that you feel about um your your children if you’re that big sibling. So it’s a very strong, um almost primal thing that we have with our siblings. |
| Sarah | You mentioned Megan Abbott ah in the introduction, and we spoke to her because her book that was released earlier this year, El Dorado Drive, really played with those relationships between, it was sisters in her book. |
| Brook | Three sisters. In that story, I think we see a lot of that, what I mentioned of the loyalty and the guilt because they wanted to support one another. And yet there’s some really fishy, um, potentially criminal things going on. And so do you turn in your sibling or do you just help them hide it? And that was, I really felt that tension that, uh, the characters are going through in that story. |
| Brook | Conversely, a function that siblings can provide in a story of that manipulation or almost like a dark mirror is definitely present in a book I know we both also read, which is Julie Chan is Dead, Sarah. |
| Sarah | Yeah, that’s a great example of siblings. And the premise in that one woman whose life is not turning out as well as she might like goes to visit her very successful social media influencer sister and finds her dead. And because they are twins, she takes the opportunity to assume her sister’s life. And the book is really about what happens as a result of that. |
| Brook | Mm-hmm. Mm-hmm. Yeah. And you mentioned twins and that really takes it up a notch. Like we’re not just talking about siblings, we’re talking about twins and it just seems to like concentrate or magnify all the aspects that we just mentioned. |
| Brook | I mean, we know in real life that toddler twins many times have a, their own language. You can separate twins at birth and then 30 years later find out that they have lived mirror lives. So, it’s not too much of a stretch in some of these fictionalized versions that, you know, it becomes very twisted and rather dark because that book, while it is a mystery, I think that it is definitely a ah thriller type feel to it. |
| Sarah | Well, and I would say that You know, when I think about books that fit into this category, almost exclusively they are thrillers. |
| Brook | Mm hmm. Mm hmm. Well, the Detection Club did ban the idea of twin plots. Maybe that’s why we don’t see it a whole lot in whodunits, because they said that it was too easy of a trick, right? But I don’t know. i like stories like, say, The Prestige, which plays with the idea of twins. I think if it’s done well, it can be a really incredible twist. But there again, that story would fall into the category of a thriller, I believe, like or a a but suspenseful drama. |
| Brook | A sibling can also be used as a plot device. Like they’re the accused that gets an amateur sleuth involved in taking on the case. |
| Brook | ah Lord Peter Wimsey goes through this in Dorothy L. Sayers’ Clouds of Witness because his brother Gerald is accused of a murder. And so Lord Peter must investigate this and clear Gerald’s name. And it the stakes are even higher because Gerald is the Duke of Denver. |
| Brook | And so in order to actually save the whole family’s name, um Lord Peter Wimsey is compelled to help. As an author of cozy mysteries, you’re always looking for that good reason to get the amateur sleuth involved. And I think, you know, the loyalty and the responsibility to clear a sibling’s name is is a great opportunity. |
| Sarah | Oh, definitely. and And I think it um works even if they don’t have the strongest relationship. |
| Brook | Yes. Yes. And sometimes you see those are the stories at the end that they are brought back together again. So you have some character growth along the way. |
| Sarah | Another sibling relationship ah is the step sibling relationship. And that features in Such Charming Liars by Karen M. McManus. So this is a YA novel. It’s a stepbrother and a stepsister who do not have a particularly close relationship, but end up kind of thrown together because of circumstances. And it was it was, I read it last year, it was quite good. |
| Brook | That’s a great point, Sarah, because step-siblings, then um maybe they don’t have all that loyalty that you do with the siblings that you spent your whole life growing up with. or Yeah, that’s that’s a great ah kind of like side topic to the to the relationship. |
| Sarah | So another YA book ah that I read last year is Death at Morning House. And this was by Maureen Johnson. She often writes stories that have a present day and a historical um mystery as well. And in the historical mystery, it centers around a family with, I think it was six siblings, but I, i actually am not sure um that I’ve got that right. But um that’s a key ah point in that story is this, these family relationships. |
| Brook | Yeah, I haven’t read that one, Sarah, but I love Maureen Johnson. So that sounds great. |
| Brook | This year I read ah The Last Mrs. Parrish. This is by Liv Constantine. And this is interesting because the woman fakes having a sister in order to ah ingratiate herself to someone who lost a sister to a chronic disease. |
| Brook | So, um i thought that was interesting because it goes to show like how important that relationship is. And so to appear as if she went through the same loss, she yeah she made up a character in her own life. |
| Sarah | Oh, that’s a really good example, Brook. Yeah, I read that earlier this year as well. And um yeah, she really plays on having had this sister and and using that to create this this friendship with this other woman. |
| Sarah | I think, you know, when you’ve got a a large family that can, you know, you can have different relationships between the siblings. And you see that in ah Daisy Darker, where there are different siblings who returned to, i think it’s the grandmother’s house um ah for one for one evening. And so that was by Alice Feeney and published in 2022. And, you know, I think it’s not just siblings who gather, there’s other members of the family as well, but yeah you really you see that that family tension. |
| Brook | Yeah, that’s a good observation that different siblings have different relationships. So um I think about how that plays out in, say, like an inheritance mystery, ah where there’s this big group of siblings that keeps the story going that way. and you And perhaps two of them get along great, but then the there’s one that like can’t get along. and they So just watching that play out. And we’ve all I think that’s the thing about these stories is that they’re very relatable in that we’ve all either been in the situation because we come from, a say, a big group of siblings, or we’ve watched that with our friends. And um so we can just understand what that might be like if you’re put in that position. |
| Sarah | Yeah, I think that’s right, Brook. It it is an accessible way to connect readers to your story because it’s an experience that a lot of people have, right? That experience of of being in a sibling relationship. |
| Sarah | And you mentioned inheritance. There’s a series… That’s another YA series by Jennifer Lynn Barnes called The Inheritance Games. And it centers around brothers who um belong to this quite wealthy wealthy family. And um they are very different characters. |
| Brook | Fun. |
| Sarah | But they have this, because they are brothers, they have this loyalty that almost feels, you you know, despite the tensions that they have with each other, they will stick up for each other when faced by, you know something external. |
| Brook | Yeah. And that’s very real life. And speaking of that, i think we can’t talk about this topic without mentioning a true crime example, which is Lizzie and Emma Borden, ah the infamous Borden case, which remains unsolved to this day and one of the most discussed sibling-related crimes in history. |
| Brook | This happened in 1892, predates anything that we’ve talked about except ah “Fall of the House of Usher,” I suppose. And Lizzie was accused and acquitted of killing their father and stepmother. |
| Brook | But Emma remains kind of this shadowy, loyal sister figure um who certainly knew more than she talked about. And i think that dynamic really continues to inspire are our fiction today. |
| Sarah | Yeah, that’s um that’s a great example. And yeah unfortunately, there are um real life examples of ah family disputes that turn out badly. |
| Brook | Mm-hmm. |
| Sarah | um And I don’t think that this is based on a real story, but Catherine McKenzie, who we had as a guest on the show, wrote a book in 2021 called Six Weeks to Live. |
| Sarah | And it features sisters as they are um as their mother is dying. So they’re, they’re adult, these triplets who their mother is dying, but she actually thinks she’s been poisoned. |
| Brook | That sounds fascinating. |
| Brook | Well, we definitely also see this ah trope on screen and recently I watched the series, The Better Sister and This is on Netflix and it’s based on an Alifair Burke book by the same title. That book was released in 2019. But this is where an estranged sister duo have to reunite to unravel ah mystery um because one of the sister’s husbands is murdered and that man just happens to be the ex of the other sister. So, wow. |
| Brook | All the… strife intention that we talked about right up front is packed into this and I have not read the book yet, but the entire time I watched the series I sat there thinking I want to watch this book because I have I want to read this book because I have a feeling that ah it’s probably much more expanded and ah Even better twists along the way. |
| Brook | ah There’s only so much you can do on screen. |
| Sarah | Yeah, that’s a um that’s a great example. It plays with the trope that we mentioned with Julie Chan is Dead, where there’s siblings, one who is successful and one who is not. |
| Sarah | And, you know, then you layer on the fact that they’ve both been married to the same man. I enjoyed watching that. |
| Brook | Yeah. |
| Sarah | Well, Brook, thank you. It has been so great to discuss siblings with you and the different ways that they turn up in mysteries. |
| Brook | It has been so much fun, but you know what? It’s not the only exciting thing that we have happening this week, right, Sarah? This week on Friday, November 14th, our very first collaborative mystery that Sarah and I wrote together will be releasing. |
| Sarah | I’m really looking forward to it being out in the world, Brook. |
| Brook | That’s right. We hope you go out and pick up a copy of Life or Delft. This is going to be the first in a series called the Delft Valley Mysteries. And we’re just so excited that it’s out going to be out into the world and available for mystery lovers like you. |
| Brook | So thanks for joining us today Clued in Mystery. I’m Brook. |
| Sarah | And I’m Sarah, and we both love mystery. |
