"...the comedy never overshadows this smart, many-layered thriller... a clever plot that will keep readers guessing to the very end."

"Totally original, a sheer roller coaster ride, packed with waves of humor and a dynamic duo. Karp shows a master’s touch in his debut."

"Better than mostly anything on the market...The Rabbit Factory is, quite simply, stunning... 632 pages of unadulterated magic."

I started as a kid. Letters, song parodies, funny stuff. And once I started writing, I couldn’t stop. My college newspaper, direct mail, print ads for a bank, TV commercials for life insurance, jingles for Coke, websites, blogs, camp letters, wedding toasts, speeches, lyrics, a diary, a play (Squabbles), dozens of sitcoms, an animated special, a feature film (Just Looking), and most recently, books. Five on my own. Seven with James Patterson. (I’m especially partial to serial killers and cops with a sense of humor.) I love to write, and if you found my site, you probably read something I wrote and wonder what else did this guy do. Look around. Maybe you’ll find something you want to read. Thanks.

…brings to mind Robert B. Parker, Janet Evanovich, Dean Koontz, Stuart Woods and a lot of other fast-paced authors.
—Janet Maslin, The New York Times Book Review for The Rabbit Factory
Marshall Karp is the Woody Allen of the murder mystery. He’s up there with Carl Hiaasen and Donald Westlake and Janet Evanovich—smart, fast-paced, clever, and really, really funny.
—Joseph Finder, New York Times bestselling author
I strongly suspect that Marshall Karp is the secret love-child of Raymond Chandler and the Marx Brothers, with some Dorothy Parker around the edges. Karp should be considered a national treasure.
