In "Stone Cold," Shelter is the antagonist and is presented as an evil person in the book. He is a military veteran, and is angry at being discharged after years of service.
The book "Stone Cold" was written by Robert Swindells and published in 1983. It tells the story of Link, the protagonist, and Shelter. Both are nicknames, and the reader never learns the given names of these characters.
Shelter has grandiose plans of cleaning up the streets of London by getting rid of the homeless. To do this, kills them to populate his own army. He keeps the bodies under the floor in his apartment.
Estranged from his family, Link finds himself in London and homeless with his friend Ginger. Shelter meets the two on the street and decides they are his next victims. He lures Ginger to his home and kills him. A chance encounter brings Shelter and Link together, and Shelter convinces Link to return to his house. Because he is stronger, Link manages to overcome Shelter when he attacks. The police are called and Shelter is taken into custody. The story ends with Link questioning the fairness of the outcome and why he is still homeless while the criminal has a warm place to sleep and three meals a day.
