Harry and Freya, an ordinary couple, dreamed for years of finding something priceless buried amongst the tat in a car boot sale. It was a dream they knew in their hearts would never come true – until the day it did . . . They buy a drab portrait for twenty pounds for its beautiful frame, planning to cut the painting out. Then, studying it back at home, there seems to be another picture beneath, of a stunning landscape. Could it be a long-lost masterpiece from 1770? If genuine, it could be worth millions. One collector is certain it is genuine. Someone who uses any method he can to get what he wants. Detective Superintendent Roy Grace finds himself plunged into the unfamiliar and rarefied world of fine art. Outwardly it appears respectable, gentlemanly, above reproach. But beneath the veneer, he rapidly finds that greed, deception and violence walk hand-in-hand. And Harry and Freya are about to discover that their dream is turning into their worst nightmare . . .
