Close to Lopez de Hoyos 140 in Madrid, I found today this second hand bookshop. It must have opened recently, its address is not listed on its website. There are several shelves devoted to crime fiction and I found a book I’ve been searching for quite some time. El inocente (The Innocent) by Mario Lacruz (Planeta, 1985) 208 pages. ISBN: 84-320-8636-3. Stay tuned.
