Roberto Saviano’s ZeroZeroZero, an examination of the cocaine trade, debuted at #1 in his native Italy in April, knocking another famous Italian writer, Andrea Camilleri, from #1 to #5. Saviano is best known in the U.S. for Gomorrah, his exposé of the Camorra—the Naples crime network—that was adapted for the big screen. The translation was done in 2007 by FSG and has sold 35,000 copies in the U.S., according to Nielsen BookScan.

Germany’s #2 fiction title, The Devil’s Cave by Martin Walker, will be published this July by Knopf. The novel is the fifth in the Bruno, Chief of Police series; the previous four novels were also published by Knopf, beginning in 2009. Together, the four books have sold over 30,000 copies in the U.S. at the outlets reporting to BookScan.

Last month’s #1 title in the Netherlands, Stoner by John Williams, slipped to #2 as Jussi Adler-Olsen’s The Marco Effect took the top spot. Adler-Olsen, a mainstay on the Dutch chart, has had a few books published stateside by Penguin through the Dutton and Plume imprints, and has two new mysteries in May 2013: the paperback edition of The Absent One was released May 7, and A Conspiracy of Faith will publish May 28.
