hero worshipper

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

'leander literally' is the definition.
(Leander was the lover of Hero in mythology)

'man keeping quiet in dispute over killer' is the wordplay.
I cannot quite see how this works, but
'man' could be 'hero' (I have seen 'Courageous man' mean 'hero' so perhaps 'man' could also mean 'hero') and 'hero' is located in the answer.
'quiet' could be 'sh' (both can be said to tell someone to be quiet) and 'sh' is present in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found within the answer.
'killer' could be 'ripper' (Jack the Ripper) and 'ripper' is present in the leftover letters.
A single letter 'w' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'the' is the link.

Can you help me to learn more?
