Doctor finds silicon residue from the killer

The Doctor and Romana arrive to discover De Vries and Martha brutally murdered in the entrance hall, their remains scattered among the wreckage of furniture. The Doctor examines the corpses and notes the brutal nature of their deaths, then turns to K9 as the robot provides forensic evidence of a silicon-based murder weapon. K9’s identification of the white powder residue and the trail it leaves signals the presence of a supernatural assailant connected to the Cailleach’s dormant ritual. This confirmation forces the Doctor to recognize the immediate threat posed by the ancient entity’s awakening and the unnatural forces now loose in the world.
