Run a faultless service around the camp (7)
I believe the answer is:
scamper
'run' is the definition.
(I know that scamper is a type of run)
'a faultless service around the camp' is the wordplay.
'a faultless service' becomes 'ser' (I can't justify this - if you can you should believe this answer much more).
'around' is an insertion indicator.
'ser' enclosing 'camp' is 'SCAMPER'.
Can you help me to learn more?
(Other definitions for scamper that I've seen before include "Run about briskly" , "Skip playfully with campers" , "Skip about briskly" , "Skip around" , "Run along quickly" .)
