Beyond the genteel galleries and upmarket auction houses of the art world lies a darker dimension: a world of incalculable wealth, social ambition, and occasional subterfuge. Detective Philip Mould, journalist Fiona Bruce and a team of scientists investigate a new batch of potential fine art forgeries.

Portraits
This episode looks at three works of art: an 18th-century portrait of a young lady which may have been painted by society artist Philip Mercier; a sketch of a man possibly done by German artist Adolph von Menzel; and an early portrait that may have been created by Willem de Kooning.
