Direct telephone connection in hotel complex (7)
I believe the answer is:
hotline
'direct telephone connection' is the definition.
I know nothing about this answer so I can't judge whether this works.
'in hotel complex' is the wordplay.
'complex' is an anagram indicator.
'in'+'hotel'='inhotel'
'inhotel' with letters rearranged gives 'HOTLINE'.
Can you help me to learn more?
(Other definitions for hotline that I've seen before include "Direct phone access (for presidents?)" , "Direct telephone link between two officials" , "Former direct phone line between the White House and the Kremlin" , "Communications link" , "Emergency blower" .)
