What stalker does for walks, oddly (6)
I believe the answer is:
prowls
'what stalker' is the definition.
I can't judge whether this defines the answer.
'for walks oddly' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
The alternate letters of 'walks' are 'wls'.
'pro'+'wls'='PROWLS'
'does' is the link.
Can you help me to learn more?
(Other definitions for prowls that I've seen before include "Moves stealthily or loiters about" , "Walks about stealthily" .)
