Miranda Monkhouse's boy (5)

I believe the answer is:

damon

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

'boy' is the definition.

'miranda monkhouse's' is the wordplay.
'DAMON' is hidden in amongst the letters.
But, I'm uncertain how this is indicated.

Can you help me to learn more?

(Other definitions for damon that I've seen before include "faithful friend" , "Pythias's friend" , "Writer Runyon's first name" , "Matt --, US actor" .)

I've seen this clue in the Evening Standard.
