the novel is a day in a girls life as she travels around Soho/west London searching for a male friend (a gay guy!?) and descibes scenes from her life, she is a semi-alcoholic and a nymphomaniac!. she has problems getting around because of some event on the tube
at the end of the novel, it turns out that the guy she is searching for died (commited suicide) under the wheels of a tube train!.
