Series of programmes in which antiquarian book dealer Rick Gekoski tells the stories that lie behind five very different missing works of art.

Architect, designer and artist Charles Rennie Mackintosh is internationally celebrated as one of the most significant talents of the late-19th and early-20th centuries. His creative genius and contribution to modern architecture and design is unquestioned, with his design for the Glasgow School of Art undoubtedly his masterpiece. But commissions were few and support for his work limited.

Rick examines Mackintosh's life and work and asks why he received so little support during his lifetime.
