'All-star' assortment that includes Everyman: sense a problem? (5,1,3)
I believe the answer is:
smell a rat
'sense a problem?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'all-star assortment that includes everyman' is the wordplay.
'assortment' indicates an anagram.
'that includes' means one lot of letters goes inside another.
'everyman' becomes 'me' (where the crossword setter is 'Everyman').
'all'+'star'='allstar'
'allstar' is an anagram of 'sllarat'.
'sllarat' enclosing 'me' is 'SMELL A RAT'.
Can you help me to learn more?
(Other definitions for smell a rat that I've seen before include "Become suspicious" , "Sense something is amiss" , "Suspect deception" , "Detect something suspicious" , "Find something fishy" .)
