Sports distressed satchel with note inside (9)
I believe the answer is:
athletics
'sports' is the definition.
(thesaurus)
'distressed satchel with note inside' is the wordplay.
I cannot really see how this works, but
'note' could be 'ti' (musical note as in do re mi fa so la ti) and 'ti' is located in the answer.
an anagram of 'satchel' is 'athlecs' which is within the left over letters.
No letters remain.
This explanation may well be incorrect...
(Other definitions for athletics that I've seen before include "Track and field events" , "Running and jumping" , "on the track, perhaps" , "Physical sports for trained competitors" , "Lithe acts observed in sporting contests" .)
