The second Catrin Sayer Mystery. A retired clergyman collapses in the Kelvingrove Museum in Glasgow. It is thought to be a heart attack until the angina medication he took at the onset of the attack is discovered to be a placebo; it was totally ineffective. A drug 'baron' in Glasgow searches out the services of a friend of his late father, an art forger. He has a job for him.Detective Constable Catrin Sayer is now nearly a year into her assignment with the Art Crime Unit at New Scotland Yard. The journey north to Glasgow on a new case is tied to both the death of the clergyman and a rumour of theft or fraud associated with paintings by a group of artists known as 'The Scottish Colourists'.
