This proved to be my most popular post since I switched to WordPress, but still no one has identified number 6.
From the left top the writers were:
Frances Fyfield, Liza Marklund, Asa Larsson, Karin Alvtegen
Mari Jungstedt, number 6, Yrsa Sigurdardottir, Camilla Lackberg
Karin Fossum, Esther Verhoef, Dominique Manotti, Helene Tursten
Agatha Christie, Val McDermid, Saskia Noort, Fred Vargas
Six Swedish, two English, two Dutch, two French, one Norwegian, one Icelandic, one Scotttish and one ?? female crime writers.
Who is number six?
