Novelist Laura Lippman sold 4,739 eBook copies and 4,000 hardcover copies of I’d Know You Anywhere since her new thriller went on sale August 17th.

The Wall Street Journal spoke with HarperCollins senior VP Frank Albanese about the new development. He explained: “This is the first book of ours of any consequence that has sold more e-books than hardcovers in the first week … What we’re seeing now is that if a book gets a good review, it gets a faster lift on the digital side than it does on the physical side because people who have e-readers can buy and read it immediately.”

Lippman (pictured, via Jan Cobb) has some strong critical support. The Washington Post ended a recent review with high praise: “Some people would segregate Lippman as a crime or thriller writer. That’s a shame. She’s one of the best novelists around, period.”
