Dicky can and must find sacred place (7)
I believe the answer is:
sanctum
'sacred place' is the definition.
(I've seen this before)
'dicky can and must' is the wordplay.
'dicky' is an anagram indicator (dicky can mean ill or non-functioning).
'and' says to put letters next to each other.
'can'+'must'='canmust'
'canmust' with letters rearranged gives 'SANCTUM'.
'find' is the link.
(Other definitions for sanctum that I've seen before include "Sacred place; private room" , "Room safe from disturbance" , "Private place, may be inner" , "Sacred area" , "sacred space" .)
