Suspect Brian Lara briefly touring India is one who might quieten the crowd? (9)
I believe the answer is:
librarian
'one who might quieten the crowd?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'suspect brian lara briefly touring india' is the wordplay.
'suspect' indicates an anagram (a suspicious or unusual spelling).
'briefly' means to remove the last letter.
'touring' indicates putting letters inside (tour can mean to go around).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'brian'+'lara'='brianlara'
'brianlara' with its last letter removed is 'brianlar'.
'brianlar' with letters rearranged gives 'libraran'.
'libraran' enclosing 'i' is 'LIBRARIAN'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for librarian that I've seen before include "Bookish type" , "Person working with books" , "Custodian of a collection of books" , "Philip Larkin was one at Hull University" , "job!" .)
