Editor Morgan briefly stopped by editor Philip - he's a danger to children (4,5)
I believe the answer is:
pied piper
'editor morgan briefly stopped' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'by editor philip he's a danger to children' is the wordplay.
I cannot really see how this works, but
'by' could be 'per' (I've seen this in another clue) and 'per' is found in the answer.
'he' could be 'ed' (short for Edward) and 'ed' is present in the answer.
'philip' could be 'pip' (can be a nickname for Philip) and 'pip' is found within the answer.
A single letter 'i' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pied piper that I've seen before include "Hamelin abductor" , "(Hero of) Browning poem" , "One who lured" , "One who enticed children" , "Legendary German musician who lured away rats and children in Hamelin" .)
