CLEVELAND (AP) ― The man who famously put aside his Big Mac to help rescue three women held captive in a Cleveland house for over a decade has signed a contract to publish his memoirs.

Charles Ramsey signed the deal with the Cleveland publisher David Gray & Co. on Thursday.

Amanda Berry, Gina DeJesus and Michelle Knight and Berry’s 6-year-old daughter escaped to freedom May 6.

Collaborating as Ramsey’s coauthor will be freelance writer Randy Nyerges.

The former U.S. Senate staff speechwriter cowrote “Day of the Dawg,” with former Cleveland Browns defensive back Hanford Dixon.

“What you saw on TV doesn’t even begin to tell the story,” Ramsey said in the company’s announcement of the signing.

Ramsey and Nyerges started work on the book early this month, David Gray said. Ramsey, who had been working as a dishwasher, is devoting full time to the project.

“Charles says outrageous things, but what a story he has,” Nyerges said. “America doesn’t know yet how truly brilliant this guy is.”

The book, which does not yet have a title, will be published next spring.

“He’s completely unfiltered,” Gray said, according to The (Cleveland) Plain Dealer. “I think that’s part of his appeal. He says what he thinks. I am really intrigued by him ― as a person, with the story he had to tell, and with his ability to tell it.”

Last May, Ramsey, 44, heard screaming from Ariel Castro’s Seymour Avenue house next door. Ramsey ran over, helped a woman who said she was Amanda Berry escape through the front door, and called police.

He was hailed as a hero, and his animated TV interviews, offering blunt opinions on race, class and life in the inner city, made him a sensation.
