Fiona Bruce and the experts head to the banks of the Cyde to meet visitors bringing family heirlooms to the 18th-century cotton mill of New Lanark. As evidence that you should never throw anything out,treasures featured include a pearl necklace bought cheaply at a boot sale, a valuable clock found in a flea market, and a rare cuddly toy found abandoned in a skip. Plus there is a moment of disquiet when a guest reveals how a family painting is a reminder of an uncomfortable family secret that dates back to the days of Nazi Germany.

Fiona Bruce and the team are in the grounds of BBC Caversham near Reading.

Items featured include a communion book originally owned by the poet Wilfred Owen, an Aston Martin first driven by an RAF group captain in World War II, and a remarkably well preserved, finely embroidered stumpwork box from the 17th century that brings gasps of delight and surprise when its value is announced.
