Dr Bendor Grosvenor discovers a small portrait of Rembrandt in the collection of a National Trust house, Knightshayes Court in Tiverton, Devon. The painting is thought to be a later copy of a self-portrait by Rembrandt now in the Rijksmuseum in Amsterdam, but Bendor believes it is in fact a study for the finished picture by Rembrandt himself.

At the Manchester Art Gallery, Dr Bendor Grosvenor discovers a painting of a country gentleman from the 1770s which he believes has been wrongly attributed to Nathaniel Dance. He feels sure it is in fact by the German painter Johann Zoffany, a favourite portraitist of the royal family under King George III.

Petworth House in West Sussex is one of the great Baroque treasure houses of England, and Dr Bendor Grosvenor finds two paintings which he feels warrant investigation: a portrait of a lady from Genoa which was once attributed to Rubens, but Bendor is convinced is by Anthony van Dyck, and a portrait of a young cardinal in the style of Titian, which Bendor believes may be by Titian himself.
