Reading certainly offers more than just good stories and interesting characters. Some examples might be history lessons, moral and social issues and geography. Campbell Armstrong gives the reader a generous helping of what it is like in Glasgow, Scotland in December: wet, very cold, experiencing gentrification and interesting detectives trying to deal with the ever-present crime problem. Detective Sergeant Lou Perlman, a fifty-something long time member of the Strathclyde Police department, loves his city and utilizes all of his intelligence and talents to reduce the impact of grizzly homicides. There is enough action to keep things interesting, nasty villains, honorable co-workers and personal baggage to offer the reader a positive experience. Number two in the series now goes to the top of the reading list.
