Crossword Genius

Criminal corpse is on file (10)

Ross

I believe the answer is:

procession

'file' is the definition.
(thesaurus)

'criminal corpse is on' is the wordplay.
'criminal' indicates an anagram.
'corpse'+'is'='corpseis'
'corpseis' with letters rearranged gives 'processi'.
'processi'+'on'='PROCESSION'

(Other definitions for procession that I've seen before include "Parade, cavalcade" , "Motorcade" .)

I've seen this clue in The Telegraph.
