After leaving prison, Stone concentrated on work in the community and being an artist, a hobby he began in the Maze. His paintings are vivid and not so much political as topical. They fetch between a few hundred and a few thousand pounds each. Stone published his autobiography, entitled "None Shall Divide Us", in which he claimed that he had received "specialist assistance" from RUC operatives in carrying out the cemetery killings. A second book and the auctioning of the jacket he wore at the Milltown Cemetery at a Scottish loyalist club for £10,000 resulted in legislation to ban convicted paramilitaries released through the Northern Ireland peace process from profiting from their crimes.
