Redeployment of PCs later characterised by haunting fear? (8)
I believe the answer is:
spectral
'characterised by haunting fear?' is the definition.
(spectres are ghosts)
'redeployment of pcs later' is the wordplay.
'redeployment of' indicates an anagram (letters deployed to new locations).
'pcs'+'later'='pcslater'
'pcslater' is an anagram of 'SPECTRAL'.
(Other definitions for spectral that I've seen before include "Like a colourful band" , "Rap Celts for being ghostly" , "Ghostly; of bands of colour" , "Spooky" , "Of or like a ghost" .)
