In Costa del Sol, southern Spain, 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 to Spain from St Petersburg, holding the corpses of nine women. Now Antonia, with the help of her protector, 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.
