Disturbing spectre enveloping man - leading to these? (3,6)
I believe the answer is:
the creeps
'these?' is the definition.
The definition suggests an adverb but the answer is not.
'disturbing spectre enveloping man' is the wordplay.
'disturbing' indicates anagramming the letters (I've seen this in other clues).
'enveloping' indicates putting letters inside.
'man' becomes 'he' (pronoun for a man).
'spectre' is an anagram of 'tcreeps'.
'tcreeps' going around 'he' is 'THE CREEPS'.
'leading to' acts as a link.
(Other definitions for the creeps that I've seen before include "Unease" , "uneasy feeling" .)
