I found this informative article at Crimereads Weekly, which intrigued me because my mystery series, A Caulfield, Sheridan Mystery, also has a “crime-fighting duo.”
“Must-Read Crime-Fighting Duos” by Darynda Jones, New York Times & USA Today Bestselling Author of the Charley Davidson Series, April 15, 2020
“Teamwork, as they say, makes the dream work, and there is little in fiction more fun than a crime-fighting duo. Duos come with their own set of conflicts, their own chemistry and layers and texture. Watching those aspects unfold on the page adds a richness and depth to a story that wouldn’t be there otherwise, no matter how well-drawn the mystery.”
First on her list are Sherlock Holmes and Dr. John Watson: “The penultimate of crime-fighting duos…. “The first book, A Study in Scarlet (1887) is well worth the read,” says Ms. Jones.
Her second choice is one I’ve never heard of, but certainly intend to read: Mary Russell and Sherlock Holmes: “She challenges Holmes effortlessly and, eventually, finds her way into his heart.”
Third on her list: Eve Dallas and her soon-to-be beau, billionaire CEO Roarke in mysteries by J.D. Robb (Nora Roberts): “One thing that is interesting about this team, besides their ever-evolving romance, is each character’s backstory. Their histories are dark and intriguing and create a beautiful backdrop for the tapestry that Ms. Robb weaves,” Ms. Jones writes.
Tarabotti and Maccon in The Parasol Protectorate series by Gail Carriger come in as her fourth selection: Soulless is, for Ms. Jones, “a highly recommended humorous comedy of errors” including a vampire and a werewolf.
In fifth place is the “unstoppable team” of Rizzoli and Isles, also well-known to TV fans. Ms. Jones says, “Their chemistry is unsurpassed and if you find yourself wanting to be besties with them, don’t worry. Everyone does.”
Agatha Christie’s legendary detective Hercule Poirot and his loyal, if not somewhat naïve, companion and chronicler, Captain Arthur Hastings are Ms. Jones’s sixth choice. She might also have mentioned Ariadne Oliver, for whom one detective in my novels is named.
Bones and Booth, characters by Kathy Reich, a forensic anthropologist who is teamed up with an FBI Special Agent, are Ms. Jones’s seventh selection.
Robert Galbraith (JK Rowling’s) Cuckoo’s Calling (2013) introduced PI Cormoran Strike and his secretary Robin Ellacott; they are the eighth choice.
In ninth place are characters in a paranormal mystery series by Jim Butcher: Harry Blackstone Copperfield Dresden is a PI and a wizard, whose partner is Karrin Murphy, assigned to unexplainable cases.
Last but not least are Thomas and Charlotte Pitt in Anne Perry’s Victorian crime series.
