He conducts confusing hotel ruse (5)
I believe the answer is:
usher
'he conducts' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'confusing hotel ruse' is the wordplay.
'confusing' is an anagram indicator.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'h'+'ruse'='hruse'
'hruse' is an anagram of 'USHER'.
Can you help me to learn more?
(Other definitions for usher that I've seen before include "Show in - escort" , "whose house collapsed?" , "Doorkeeper in court of law" , "One who should lead the way" , "falling house" .)
