'Threshold' (1 Part) by Paul Finch

After the mysterious events at Coal Hill School, the British government has created the Counter-Measures group, a specialist team that investigates strange phenomena and dangerous technology. Their first missions will involve a haunted warehouse, a ground-breaking artificial intelligence, a mysterious new town and a threat to the future of the country...

A missing scientist and ghostly phenomena bring Gilmore and Allison to a factory in Bermondsey, and the discovery of a science that should not exist. As Rachel Jensen returns to help them, a new future for Counter-Measures is set in motion...
