Hallam is almost over the sudden death of his mother when he begins to suspect that his beautiful step-mother may have had a hand in her death, and it doesn't help that Hallam fancies her rotten. After a confrontation with his step-mum, Hallam escapes to Edinburgh. Out of money and out of friends, he finds his tree-top skills well suited to the rooftops of the city, where he lives ferally, attempting to avoid the perils of the streets below and becoming obsessed with a gorgeous girl who happens to look just like his mother.
