Trump's lawyer questioned one of E. Jean Carroll's books during his trial. Copies are now selling for thousands.

During the second defamation case brought by writer E. Jean Carroll against former President Donald Trump, his attorney drew attention to one of her books — a little-known 1980s work called "Female Difficulties: Sorority Sisters, Rodeo Queens, Frigid Women, Smut Stars and Other Modern Girls."

Trump lawyer Alina Habba asked Carroll in court last week to explain the title of her book, a collection of essays, with the attorney trying to show that the writer had once written about "smut stars," according to Business Insider. The line of questioning went nowhere, with the judge sustaining an objection from Carroll's attorney. 

But the mention of Carroll's book during the closely watched trial has had one tangible result: Used copies of the book are now fetching thousands of dollars. On Friday morning, a used copy of "Female Difficulties" was listed for about $2,141 on used book site AbeBooks, but by Friday afternoon the book was no longer available. Another copy was available on Amazon for $999.99. Bibio is selling a copy for $199.
