In an interview for the paper's "By The Book" column, the 74-year-old Walker said Icke's 1995 book " And the Truth Shall Set You Free" was one of the volumes on her nightstand.

"In Icke's books there is the whole of existence, on this planet and several others, to think about," Walker said, calling the book "a curious person's dream come true."

Icke, 66, is a British author and former professional soccer player who is best known for espousing the theory that Earth is controlled by a race of reptilian creatures who are able to take human form. In "And the Truth Shall Set You Free," Icke questions whether the Holocaust happened, says the Talmud is "among the most appallingly racist documents on the planet," and claims that far-right groups in the U.K. are fronts for the Israeli secret service Mossad and the Anti-Defamation League (ADL).

Writing in Tablet magazine, commentator Yair Rosenberg called "And the Truth Shall Set You Free" "an unhinged anti-Semitic conspiracy tract written by one of Britain's most notorious anti-Semites ... Indeed, the book was so obviously anti-Semitic that Icke's publisher refused to publish it, and he had to print it himself."
