Actor Lana Wood will address the drowning death of her sister, movie star Natalie Wood, in a new memoir, the Hollywood Reporter reports.

Lana Wood’s Little Sister: My Investigation Into the Mysterious Death of Natalie Wood will be published by Dey Street Books this fall.

The publisher describes the book as “a no-holds-barred account of the life and death of her sister, Natalie Wood, including exclusive new information from people directly involved in the investigation.”

Natalie Wood, known for her iconic performances in films like Rebel Without a Cause and West Side Story, drowned off Catalina Island in 1981, while on a trip aboard her husband Robert Wagner’s yacht. The manner of death was initially ruled an accident, but the boat’s captain, Dennis Davern, later said he believed Wagner murdered her, a suspicion that Lana Wood shares.

In 2018, Wagner, now 91, was named a “person of interest” in Natalie Wood’s death. He has never been charged with a crime in association with the drowning.

“I’ve waited 40 years to finally unburden myself about what happened to my sister Natalie Wood,” Lana Wood said. “I’m finally sharing everything I know now and what I knew then but was not ready to or brave enough to reveal. This book will shed new light on my life with Natalie, leading up to, and culminating in the events surrounding her death.”

Little Sister is slated for publication on Nov. 9.
