The longtime companion of posthumously best-selling author of the Millennium trilogy, Stieg Larsson, says she's disappointed she was shut out from the film adaptations of the books.

Eva Gabrielsson, Larsson's partner of 32 years until his untimely death in 2004, wrote "There Are Things I Want You to Know: About Stieg Larsson and Me" as a response to the controversy surrounding her involvement in the novels.

She said many of the ideas, events and characters in "The Girl with the Dragon Tattoo," "The Girl Who Played With Fire" and "The Girl Who Kicked the Hornet's Nest" came from her.

"I wasn't taking part in the actual writing," Gabrielsson told CTV's Canada AM from New York in an interview that aired Wednesday. "I contributed instead with content and that contribution was done along the years we were together."

Larsson, who died suddenly in 2004 at the age of 50, sold the rights to his trilogy to a Swedish publisher shortly before his death. Ever since, Gabrielsson has been embroiled in a legal battle over his multi-million dollar estate with his father and brother.

Because of a bizarre quirk in Swedish law, Gabrielsson didn't have any legal right to Larsson's inheritance because Sweden doesn't make provisions for common-law couples.

The books have been made into popular films in Sweden that have grossed millions worldwide. A Hollywood adaptation of "The Girl with the Dragon Tattoo" is expected to hit theatres this December.

What bothers her, she said, is the fact that she's been shut out from the production of the films.

"It's not just the money, they also have control of the quality of the translation and what goes in," she said. "That's what's troubling me. ... They can take the money."

Gabrielsson also said she has no plans to attempt to write a fourth novel in the series.

"I think people should come to terms that Stieg is actually dead and there are three books that were finished by him and let's leave it at that," she said.

As for rumours that she has the laptop with a nearly finished fourth novel written by Larsson, she said that's nonsense.

"I don't have the laptop -- people assume I have the laptop but I don't have it," she said.

Her book, she said, focuses on their life together and attempts to give something back to the readers of the series.

"It's personal but universal," she said. "The life we had, the people we met, the character traits we had… I tried to keep things that were really personal to myself."
