G. T. Karber

Gregory Thomas Karber is an American writer, best known as author of the Murdle series of murder mystery puzzle books and its accompanying website. Early life Karber was raised in Arkansas, the son of a judge and a civil rights attorney. His maternal grandfather worked as an FBI agent in San Francisco in the 1960s.

He earned a bachelor's degree in mathematics and English literature from the University of Arkansas, and a Master of Fine Arts degree from the USC School of Cinematic Arts. As of 2013, he had written five unpublished novels. Karber made a video excoriating Jeffries' comments titled "Fitch the Homeless," in which he handed out Abercrombie & Fitch clothing to homeless people on Los Angeles' Skid Row. The video became a viral hit, earning national media coverage. While many initially applauded the video, others saw it as "backwards-ass activism" and "as insensitive as the A&F chief he's targeting." In 2016, he and Dani Messerchmidt created an online quiz called Trump or Jesus, which became a viral hit.

A mystery enthusiast, in 2022 he created Murdle, a web-based daily murder mystery game modeled on logic grid puzzles.

In December 2023, Karber undertook a U.K. bookshop tour, and appeared on BBC Radio 4's Start the Week. For Christmas 2023, Murdle was the bestselling book in the U.K., making Karber only the third non-British person to achieve that distinction, following Dan Brown and Michelle Obama. In May 2024, Murdle received the British Book Award for overall book of the year.

In January 2025, Karber announced his next family of puzzles, Bordergrams, a "spy connection puzzle" debuting in September 2025.

Personal life Karber lives in Los Angeles.
