'Sometimes I wonder, if I had known that it was going to take me fourteen years to paint this painting of the Crucifixion with Douglas as Jesus, and what it would take for me to paint this painting, would I have been as happy as I was then?'

Susan Alison MacLeod, a Glasgow School of Art graduate with a dark sense of humour, first lays eyes on Douglas MacDougal at a party in 1988, and resolves to put him on the cross in the Crucifixion painting she's been sketching out, but her desire to create 'good' art and a powerful, beautiful portrayal means that a final painting doesn't see the light of day for fourteen years.

Over the same years, Douglas's ever-more elaborately designed urine-based installations bring him increasing fame, prizes and commissions, while his modelling for Susan Alison, who continues to work pain and suffering on to the canvas, takes place mostly in the shadows. This Good Book is a wickedly funny, brilliantly observed novel that spins the moral compass and plays with notions of creating art.
