Criminal is nervous, seeing relics (9)

I believe the answer is:

souvenirs

'relics' is the definition.
('souvenir' can be a synonym of 'relic')

'criminal is nervous' is the wordplay.
'criminal' is an anagram indicator.
'is'+'nervous'='isnervous'
'isnervous' with letters rearranged gives 'SOUVENIRS'.

'seeing' acts as a link.

(Another definition for souvenirs that I've seen is " could be brought back from holiday".)

I've seen this clue in The Telegraph.
