Michael Connelly has said, “I was once told that the best crime novels are not about how a detective works on a case; they are about how a case works on a detective.” He’s got a very well-taken point. Crime fiction fans certainly want to know how a detective goes about solving a case. But they also want to see that the detective is a human being who’s affected by the work – sometimes changed by it. A believable sleuth doesn’t go easily sailing through something as horrible as murder without being affected by it and in a really absorbing mystery, the case draws the detective in and works on the detective as much as it does the reader.
Connelly should know all about this. His Harry Bosch novels are just that sort of crime fiction. For example, in The Black Ice, Bosch learns by chance of the death of fellow L.A.P.D. officer Calexico “Cal” Moore. At first the death is considered a suicide, and the word from “on high” is that Moore had “gone dirty” and killed himself as a result. But Bosch isn’t sure that it’s quite that simple. So he starts asking questions and investigating even when he’s told flat-out to leave it alone. He’s even given a set of eight other cases and a nearly-impossible deadline to keep him distracted from the Moore case. But the Moore case has gotten to Bosch. And when one of his other cases proves to have a connection to the Moore case, Bosch acts on his suspicions. He follows up on the Moore case all the way to the heart of a Mexican drugs gang and to Moore’s boyhood in a border town in Mexico. Throughout the novel we can see how Bosch is consumed by the case. It does work on him – and the reader. And when Bosch finds out the truth about Moore’s death, we see how that affects him, too. And yet, Connelly isn’t melodramatic; rather, the case consumes him in a more subtle and therefore more believable way.
Bosch isn’t the only one to be deeply affected by a case. Agatha Christie’s Hercule Poirot, for instance, has what Christie calls a very bourgeois attitude to murder: he does not approve of it. He’s even said so himself. And in many of the novels featuring him, he puts the value of human life above anything and delivers all sorts of murderers to justice. And yet there are some cases that affect him so deeply that he doesn’t quite see things like that. In One, Two, Buckle My Shoe (AKA The Patriotic Murders and An Overdose of Death), Poirot works with Chief Inspector James “Jimmy” Japp to find out who shot seemingly inoffensive dentist Henry Morley. They’re just asking questions about that murder when one of Morley’s patients disappears. And then another dies of a seemingly accidental overdose of anasthaetic. It takes time and a lot of effort, but Poirot tracks down the killer and the motive, as well as the truth behind the other events in the story. However, it’s clear that this case has affected him. He has a real sympathy for the killer and when the killer makes the case to be let free, Poirot struggles with it. But in the end, he does what he has to do. As he says to another character in the novel,
“Sometimes…I do not like the things that I have to do.”
There is even at least one novel in which Poirot is so deeply affected by a case that he lets the killer go. But no spoilers here!
There’s an excellent example of a case working on a sleuth in Maj Sjöwall and Per Wahlöö’s Roseanna, the first of their Martin Beck series. When the body of an unknown woman is dredged up from Lake Vättern, Martin Beck and his team are sent to help the local police find out who the woman is and who killed her. It takes quite a long time, but they finally discover that the woman is twenty-seven-year-old Roseanna McGraw, an American who was touring Sweden when she was killed. Once the team discovers who the woman was, they plunge more deeply into the case and as time wears on, we can see how Martin Beck is affected by this woman. You might even say he’s haunted by her and challenged to find her killer. In the end, and after patient police work, Martin Beck and his team track down the person who murdered Roseanna McGraw and it’s clear when that happens how much this case has affected the sleuths.
Ruth Rendell’s Reg Wexford is very much worked on by a case in Simisola. One day, Wexford gets a call from his doctor, who’s worried about his daughter. Dr. Akande’s daughter Melanie has apparently disappeared from the Employment Service Job Center (EJS), where she had an appointment with a job counselor. She kept her appointment but never made it home. At first, Wexford thinks that Melanie Akande may have simply gone off somewhere; she’s a young adult with her own life. But then, Annette Bystock, the job counselor with whom Melanie Akande met, is found murdered in her bed. Now it looks as though something more is going on than a young woman taking off to “do her own thing.” Then, the body of an unknown woman is found in a local woods. At first Wexford thinks it’s Melanie Akande’s body. It’s not, though, and this adds another dimension to this case. Throughout this novel, we see how these related cases work on Wexford, affect his thinking and make him re-evaluate himself.
Simon Lelic’s Rupture (AKA A Thousand Cuts) is another example of a novel where the case works on the sleuth. In that story, newly-hired history teacher Samuel Szajkowski walks into a crowded auditorium one hot day and shoots a fellow teacher and three students before turning the gun on himself. DI Lucia May has assigned to follow up on this tragedy. She’s expected to get interviews with witnesses and “rubber stamp” the official explanation for the murders, which is that Szajkowski simply “snapped.” But as May begins to talk to the people at the school, she realises that it isn’t as simple as that. The more she learns about the case, the more she sees that the school has a strong culture of bullying and that it’s that culture, as much as anything else, that’s behind what happened on that terrible day. May is affected by what she learns about the school; it’s eerily reminiscent of her own workplace environment, in which she’s having to battle to get any respect at all for what she does. In the end, we can see clearly how she’s been affected by this particular set of shootings.
Martin Edwards’ DCI Hannah Scarlett is also affected by the cases she works. In The Cipher Garden, for instance, she and her Cold Case Review team re-open the investigation into the ten-year-old murder of landscaper Warren Howe. At first, his wife Tina seemed the most likely suspect, and she had good reason, too. Howe was an abusive and adulterous alcoholic. But Tina Howe had an alibi, so at the time of Howe’s murder, the police couldn’t make an arrest. Now, anonymous notes suggest that Tina Howe really was guilty. As Scarlett and her team look into the case, they learn more and more about the Howe family and what they learn affects Scarlett deeply. So does what the team learns about the history of the town, and some of the secrets that are being kept there. In the end, Scarlett and her team find out who really killed Warren Howe and it’s easy to see how deeply she’s been affected by this case.
There are lots of other novels, too, where the case works on the detective as much as the detective works on the case. I’ve only had space for a few. What do you think? Do you agree with Connelly? If you’re a writer, how do your cases work on your sleuth?
Thanks very much to Bernadette at Reactions to Reading (and to one of her fine commentators) for the excellent comment exchange that inspired this. Oh, and thanks to Michael Connelly, too.
*NOTE: The title of this post is a line from Billy Joel’s I Go to Extremes.













You have some great examples here. I think the best mysteries are not just plot driven. The characters have to grow, or at least be changed, in order to truly be interesting.
Heather – Thank you
! And I couldn’t agree with you more. Even in mysteries that focus mostly on the plot, one has to have at least an element of character development, and a sleuth simply isn’t as human if the plot has no effect on her or him.
Wow Margot…you really don’t let the grass grow under your feet when issued a challenge eh? You are indeed superwoman.
I like the photo for this one.
I’m sure it must be hard for writers to deal with this subject sensibly…obviously we can’t have policemen falling apart all over the place as no crimes would get solved…but you do expect some reaction to the things they see and have to do. I am a new fan of the Inspector Montalbano books and one of the reasons is the way he is shown to be impacted by the cases he is involved with…in WINGS OF THE SPHINX this was particularly noticable
Bernadette – Thanks for the kind words – and no, I’m not a superwoman. I was simply intrigued – really intrigued. I do that sometimes. Oh, and thanks for the kind words about the ‘photo, too. I liked that one, myself…
And you’re quite right about the balance that’s needed between having the sleuth be affected by what s/he sees and does, and having the sleuth turn into a blob of emotions or frozen into immobility. I think there’s nothing wrong with having the sleuth occasionally get furious, weep, or do something emotional. But as a general rule the sleuth also needs to be able to actually solve crimes. And yes, Camilleri’s Montalbano reflects a very nice balance when it comes to this question. He is personally affected by the cases he works (Folks, I do recommend Wings of the Sphinx). But at the same time, he pulls himself together and does his job.
Harry Bosch is affected by most of his cases, or he wouldn’t be a special detective, one who is so popular with mystery readers. He doesn’t play by the book nor is he an automoton. He has feelings. Cases get to him.
Montalbano strikes a balance, but in August Heat, he more than does that, as the ending shows. In others he has compassion for not only victims, but sometimes for the suspects, depending on the situation.
Guido Brunetti sometimes thinks a lot about the victims and has sympathy for them and goes the extra mile to find out what happened to them. Often social issues arise. In Drawing Conclusions, Brunetti’s personal feelings for his spouse, Paola Brunetti, are stirred to the surface, and his romantic side is apparent, as he pursues the suspect.
V.I. Warshawski is often very involved emotionally involved in the investigations she takes on, getting to know relatives of the victims, befriending families and friends. She often has a personal stake in finding the culprits.
In Hypothermia, Erlender shows his human feelings as he searches to find out what happened to two young people decades earlier, and as he investigates what he suspects was a murder, which takes up a lot of his thinking.
Kathy – I should have asked you to write this post
. You give such a thoughtful answer and so many excellent examples of the way cases can work on sleuths just as they work on cases. And you’re quite right, too. In all of your examples, we see how the sleuth gets deeply involved in a case and is affected by it. That leads to the sleuth working even harder to find out the truth about the case. And it makes the sleuth even more appealing, because we see his or her dedication; we also see the sleuth’s human side.
I do like books where the crime affects the sleuth…I know they’ve got to be hardened to a particular degree, but since I’m not in their shoes, they seem callous to me if they aren’t affected.
Elizabeth – I feel the same way. If the sleuth doesn’t have any personal reaction to any of her or his cases, it really is easy to think of that sleuth as too hardened, maybe not quite human.
Since life in general does this, it’s only natural that it would be especially difficult for crime solvers not to. Roseanna is a favorite of mine.
Patti – Oh, I love Roseanna, too. In my opinion, that whole series would make a great course in crime fiction. And you’ve got a well-taken point. In real life, people are affected by their jobs, and certainly detectives are! Why wouldn’t that be the case in crime fiction, too?
Roseanna–yes, good book, showing dedication of Martin Beck.
Thank you for the compliment, Margot. You write very good posts — which just make a reader want to enthuse over favorite detectives and tell of their human side.
On addition in Drawing Conclusions is that Guido Brunetti is so overcome by a long-time love story that it impacts his judgment in his investigation — and it brings up his own romantic feelings for Paola, the great.
And Montalbano, as I pointed out, is sometimes so swayed by a victim or by a suspect that he’s emotionally involved and can make decisions based on that, either to protect the culprit or call a doctor rather than more police.
He’s more sensitive than we usually know.
As I said but thinking more about it, Erlendur has a lot of human feeling, shown not only in Hypothermia but in The Silence of the Grave. It comes out in Outrage through Elinborg — and so well. Indridason regained my faith that male writers can write about healthy, driven, smart, hard-working and well-balanced women detectives with good home lives following a case related to women’s issues, and do it sensitively to the protagonist and to the victim.
.
Kathy – *Blush* That’s very kind of you – thank you
. You’re quite right, too, about Brunetti, Montalbano and Erlendur. All of them have appealing human sides and we can see that they are sometimes deeply affected by what they have to do and go through. Your examples also show, I think, that these sleuths have a real dedication to their work. Part of the reason they can be so affected by their cases is that dedication.
lovely post, Margot (no, you do not let the grass grow!) and nice discussion. I do identify with the title of your post. I have enjoyed many of your and the commenters’ examples. Another good one is Jan Lier Horst’s Dregs, and another again is Kjell Eriksson’s The Hand that Trembles. Both, coincidentally, concern feet – but they are different books and show how a case can exert a grip on the detective.
Maxine – Thank you
. Thank you also for mentioning Dregs. That one went on my TBR when I read your excellent review of it. It’s a really clear example I think of the way that cases can work on a sleuth. The Hand That Trembles is on my TBR list, too, thanks to your terrific review of it. And from what I’ve read of it, it’s another instance of solid characterisation. And in the end, I think that’s what it comes down to, really. If the sleuth is a solid character, s/he’s got to be affected, at least at times, by these cases.
Connelly makes a great point. One of the most interesting aspects of our favorite sleuths like Bosch is how they react to each case.
Pat – You put that very well. That’s one thing I like very, very much about a well-written sleuth, too. It separates “cookie cutter” sleuths from genuine, believable sleuths.
