In "Sentiment", Vincent O'Sullivan looks inside the lives of a group of middle-class English people just before the start of the first world war. The story centres around the love affairs of four young people and how they interact. O'Sullivan picks apart his characters' cares and concerns and shows how these are trivial when we know what was about to happen to them and their world. Vincent O'Sullivan (1868-1940) was born into a prosperous Irish American family in New York and moved to London as a child. However, Vincent spent much of his life in the demi-monde world that is the setting of many of his stories.
