Black Wolf by Juan Gómez-Jurado

The highly anticipated sequel to Juan Gómez-Jurado's number 1 international bestseller, Red Queen, featuring Antonia Scott, the most compelling and original detective since Lisbeth Salander. Translated by Nick Caistor and Lorenza Garcia.
Antonia Scott is the lynchpin of the Red Queen project, created to work behind the scenes to solve the most dark, devious and dangerous crimes.
In southern Spain, in the Costa del Sol, a key mafia figure is found brutally murdered in his villa, his pregnant wife, Lola Moreno, barely escapes an attempt to kill her and is on the run. An unusual shipping container arrives from St Petersburg in Spain with the corpses of nine women.
Now Antonia, with the help of her protector, Jon Gutierrez, must track down the missing Lola. But they aren't the only ones - a dangerous hitman, known as the Black Wolf, is also on her trail. And Antonia Scott, still plagued by her personal demons, must outwit, out-manoeuvre, and, ultimately, face this terrible, mysterious killer.
