Call round, unfortunately missing member of the House (4,5)

I believe the answer is:

lord lucan

'missing member of the house' is the definition.
(member of the House of Lords who disappeared)

'call round unfortunately' is the wordplay.
'unfortunately' indicates an anagram.
'call'+'round'='callround'
'callround' is an anagram of 'LORD LUCAN'.

(Another definition for lord lucan that I've seen is " Missing man".)

I've seen this clue in The Guardian.
