What stalker does for walks, oddly (6)

Ross

I believe the answer is:

prowls

I'm a little stuck... Click here to teach me more about this clue!

'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" .)
