Hetty Feather - Season 1 Episode 4

Matron attempts to coerce a cowed Mathias into being her spy as she sets the orphans to work making toys, supposedly destined for charities though Gus discovers that she and tradesman Cooper are planning to sell them to stores for profit and leads the others in sabotaging the goods. They are almost caught but Mathias rescues them before explaining how he returned to the hospital to avoid being sold as a slave. Matron is angry when she sees the damaged toys but, as the children are falling ill due to lead paint, humane teacher Mr Cranbourne persuades her to stop her venture, pointing out that the governors would not be happy to know about her deal with a rogue like Cooper.
