The Girl in the Spider’s Web, David Lagercrantz’s phenomenal fourth installment in Stieg Larsson’s internationally bestselling Millennium Series, has sold over 200,000 copies in hardcover and e-book during its first week of sales, publisher Alfred A. Knopf reports. The book went on sale in the U.S. on Sept. 1.

“The response from readers has been beyond what we’d anticipated and speaks to the connection readers have to this series,” says Sonny Mehta, Chairman and Editor-in-Chief of Knopf. “Lisbeth Salander is one of the most compelling heroines of 21st century crime literature, and I am thrilled to see readers have welcomed her return.”

Due to these substantial sales figures, Knopf has ordered four additional printings of The Girl in the Spider’s Web. On Sept. 8, the book debuted at No. 1 on the Barnes & Noble bestseller list. After being chosen by Stieg Larsson’s estate to continue the series, Lagercrantz, a Swedish journalist, wrote the book under measures of heavy security, working on an air-gap computer (one that has never been connected to the internet).

The original three books in Larsson’s series — The Girl with the Dragon Tattoo, The Girl Who Played with Fire, and The Girl Who Kicked the Hornet’s Nest — have sold 80 million copies worldwide.
