Uninvited - Richard House

Nine months after following a friend to London Ian Proctor isn't happy:
the squat is about to be evicted, he hates his part-time job and feels like quitting at any moment, and his friend of over twenty-two years is embroiled in a scam that clearly hasn't worked.
Nothing is secure, and his life seems to be slipping away living amongst a group of slackers in South London.
More disturbing is the violence that surrounds them; a man thrown from the back of a bus, and two thugs a little too handy with their fists and paint stripper.
Following a bicycle messenger through central London, Ian embarks on an adventure which promises much
but which is ultimately threatened by his former associations.
