The novel Saturday (2005), by the English writer Ian Mc Ewan, has instigated a deep study on modern context. The work describes a day in protagonist Henry Perowne’s life, who needs adapt to different situations and assume different “social roles”. Along this day, he experiences fear and insecurity, symptoms that torment him. It can be said then, that Saturday is situated in "Liquid Times", this means, in times when the shapes dissolve, become unstable, pour down and are molded and adapted (BAUMAN, 2007). The theoretical approaches by Giddens (2002), Baumann (2001, 2007, 2009) and Hall (2006) emphasize the current context and identities. So, the novel Saturday, through the characters, brings examples of a day in liquid times.
