Francisco González Ledesma, (Barcelona, 1927), is a writer, journalist and lawyer. When he was twelve he started to write, at fifteen he begun to earn his living as a cartoonist and as a writer of cowboys’ novels under the pen name of Silver Kane. In 1984 he won the Premio Planeta with his novel Crónica sentimental en rojo. On two occasions he obtained the Prize Mystère to the Best Foreign Novel published in France. He is probably best know in France and Italy than in Spain. Unfortunately his books are not available in English yet.
