Gary (Marshall Lancaster), works in the off cuts department at Mackintosh, and has a beautiful, expensive home, full of costly antiques and erudite scientific tomes, everything just so. The only thing that doesn't fit is him. The problem is he's had a letter from a solicitor, informing him that he had been left a house and a substantial amount of money. In his father's will. All well and good, except that the only father Gary had ever known was still alive. Both Gary and his brother Stephen (Lee Ingleby) were adopted, only their adoptive parents never got round to telling them. A bit of a shock. Especially for Stephen who got the news without the financial bonus. Suddenly strange things start happening - Gary finds a piece of paper with versions of his signature on it, although no credit cards or cheque books have been stolen; then he comes home after a day at work to find the kettle warm as if it had just been used; or there's a beer bottle top on the floor which he didn't leave there (thetvdb.com)
