Sidney receives a series of anonymous phone calls, which he realises may be linked to a series of murders in which the victims were all important community figures killed by someone who leaves dead birds as a grisly calling card. The threat forces Sidney to question whether he can reconcile his relationship with Amanda and his calling as a vicar. Leonard bonds with Hilary as she cares for her dying father, while Geordie’s investigation of the killings leads him to a mysterious home for people with disabilities.
