For more than four decades, New York Times and USA Today bestselling writers Kristine Kathryn Rusch and Dean Wesley Smith have been writing professional mystery short stories that have won awards and sold millions of copies, plus they have been acclaimed and enjoyed by fans over the entire world.

Now, for the first time, they collect 100 of their mystery short stories into a five-volume series called Crimes Collide. Fifty stories total from each author, with ten stories from Rusch and ten from Smith in every volume.

Volume 4 features non-human detectives. Beginning with Smith’s “Cat Caught in the Art,” from his Pakhet Jones series featuring a superhero in the world of cats, and ending with Rusch’s “Helmie,” in which the search for a missing cat requires magical investigation, this volume offers wild adventures and some truly strange crimes.
