On New Year's Eve 1999 progressive mental health campaigner Greg Collins was murdered and now the discovery of his diary is found, chronicling his fear of his likely fate. The team interviews his colleagues including Toni Pembury, who tells them that Greg was battling a drugs company, and Samia Khan, now a peeress, who fell out with Greg after leaving his mental health charity to set up one of her own. Then they are ordered to halt the inquiry, supposedly in the wake of the mishandled Henway case. When Greg's journal goes missing they must work unofficially to solve his murder - and work fast since UCOS is threatened with being disbanded.
