 Although Chatwin did not succeed with The Nomadic Alternative , he returned to the topic of restlessness and wandering in his subsequent books . Writer Jonathan Chatwin ( no relation ) stated that Chatwin 's works can be grouped into two categories : " restlessness defined " and " restlessness explained . " Most of his work focuses on describing restlessness , such as in the case of one twin in On the Black Hill who longs to leave home . Another example is the protagonist of Utz , who feels restless to escape to Vichy each year but always returns to Prague . Chatwin attempted to explain restlessness in The Songlines , which focused on the Aboriginal Australians ' walkabout . For this work , he returned to his research from The Nomadic Alternative .
