Scotsman in Monrovia now (3)
I believe the answer is:
ian
'scotsman' is the definition.
(common Scottish name)
'in monrovia now' is the wordplay.
'in' indicates a hidden word.
'IAN' is hidden within 'monrovia now'.
(Other definitions for ian that I've seen before include "Sir - McKellen, actor" , "Botham or Chappell?" , "Male" , "The familar Dr Paisley" , "Albert Beale's first name in EastEnders" .)
