1. Nicci French
When not being adorable, Nicci Gerrard and Sean French combine their names into one single name and use it to write crime novels. Which, oh, actually, is also adorable.
2. Michael Gregorio
The name combo strikes again, with Michael Jacob and Daniela De Gregorio. Their first novel, Critique of Criminal Reason, was a historical thriller involving the philosopher Immanuel Kant. Swoon.
3. Maj Sjöwall and Per Wahlöö
Aw, shucks, they are saying here, in Swedish, on account of together having pioneered the great tradition of dour Nordic detectives, with their Martin Beck mystery series. Also, had they gone with the shared combo-moniker “Sjöwahlöö,” we know they could have rocked that töö.
4. Aimée and David Thurlo
Clearly these two know what’s what. They have an award-winning mystery series about a Navajo woman police officer, and another mystery series about a Navajo vampire. And they have each other. And they have poodles.
5. Nancy Buckingham Sawyer and John Sawyer
As a team, their romance novel pseudonyms included Christina Abbey, Hilary London, Nancy John, and Erica Quest. WHO ARE THESE PEOPLE? Sweethearts, obviously.
6. Lars Kepler
Having agreed on a mutual pseudonym honoring both Stieg Larsson and Johannes Kepler, Alexandra Coelho Ahndoril and Alexander Ahndoril embarked on a series of crime novels. One is called The Nightmare and definitely is not about their marriage.
7. Tom Franklin and Beth Ann Fennelly
This pair of button-cute bookworms just recently co-wrote The Tilted World, a suspense novel about a lady bootlegger and the 1927 Mississippi River flood.
8. Marina Budhos and Marc Aronson
Their very impressive Young Adult book is called Sugar Changed the World: A Story of Magic, Spice, Slavery, Freedom and Science, and you might get a cavity just from the sight of them.
9. Ayelet Waldman and Michael Chabon
Generally they each work solo, unless you count her essaying about their sex life and Tweeting about him giving her HPV. But they did co-write Hobgoblin, a drama about a group of magicians trying to take down Hitler, which unfortunately has stalled out during development at HBO.
