Stupefied, enter pulsating party venue? (6,3)
I believe the answer is:
number ten
'party venue?' is the definition.
(10 Downing Street)
'stupefied enter pulsating' is the wordplay.
I cannot quite understand how this works, but
'stupefied' could be 'numb' (I've seen this in another clue) and 'numb' is located in the answer.
an anagram of 'enter' is 'erten' which is within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for number ten that I've seen before include "centre of political power" , "Last but one in" , "PM's residence" , "Downing Street address" , "Maybe X" .)
