The host behind A&E's now-defunct “Live PD,” Dan Abrams, has announced what he’s been putting his time and effort into since the show’s cancellation, and no, it’s not a reboot or another police program.

The once-popular docuseries, which followed cops on their shifts, was canceled over the summer amid the protests about police brutality. With no real talk about a return of the show or any type of spinoff in the works, Abrahams, 54, apparently put his attention and law expertise elsewhere.

On Monday, Abrams announced on Twitter that he’s been writing a book with David Fisher. “Kennedy’s Avenger: Assassination, Conspiracy, and the Forgotten Trial of Jack Ruby” will dive into the criminal trials of the man who killed Lee Harvey Oswald on live television. The book will include talk of the conspiracy theories connected to the case, as well as the details of the first major televised courtroom verdict in U.S. history.

While the book isn’t complete yet, it’s available for pre-order. It’ll be available to purchase on June 1, 2021, according to the book’s official website. The hardcover book has been priced at $28.99 and the audiobook retails for $14.99.

Customers will be able to purchase it from Amazon, Apple Books, Barnes & Noble, Books-a-Million, Bookshop.org, Google Play, Indiebound, Indigo, Kobo, Politics + Prose, and Target.

This isn’t the first book the two have teamed up to write. They’ve also penned “John Adams Under Fire,” “Lincoln's Last Trial,” and "Theodore Roosevelt for the Defense.”

Along with working on the book, Abrams has been pushing for the return of “Live PD.” In September, an arrest in a kidnapping case pursued because of a past “Live PD” episode put a fire under Abrams to get the show back on the air.

“Just another reminder that #LivePD was about so much more than some, who never saw the show, now claim. I (and many others) am continuing to push for its return and promise that I will update when we have any news,” Abrams tweeted at the time.

Abrams was also the talk on Twitter in October during the last presidential debate. One Twitter user thought he would have been the ideal moderator for President Donald Trump and President-elect Joe Biden's discussion, and hundreds of users agreed.
