Whistler carried by doddery mother out of that place (9)
I believe the answer is:
therefrom
'out of that place' is the definition.
(I've seen this before)
'whistler carried by doddery mother' is the wordplay.
'whistler' becomes 'ref' (a referee blows a whistle).
'carried by' indicates putting letters inside.
'doddery' is an anagram indicator.
'mother' anagrammed gives 'therom'.
'ref' placed inside 'therom' is 'THEREFROM'.
(Other definitions for therefrom that I've seen before include "Thence" , "Emerging from that place" .)
