A noted problem solver, I procure hotel undergoing refurbishment (7,6)
I believe the answer is:
hercule poirot
'a noted problem solver' is the definition.
I know nothing about this answer so I can't judge whether this works.
'i procure hotel undergoing refurbishment' is the wordplay.
'undergoing refurbishment' indicates anagramming the letters.
'i'+'procure'+'hotel'='iprocurehotel'
'iprocurehotel' anagrammed gives 'HERCULE POIROT'.
Can you help me to learn more?
(Other definitions for hercule poirot that I've seen before include "Christie's Belgian sleuth" , "Fabled detective" , "Agatha Christie's detective" , "Fictional Belgian detective" .)
