Drew a short space attached round entrance to cell (7)
I believe the answer is:
enticed
'drew' is the definition.
'a short space attached round entrance to cell' is the wordplay.
'a short space' becomes 'en' (typographical space as wide as an 'n').
'attached' becomes 'tied'.
'round' indicates putting letters inside.
'entrance to' indicates taking the first letters.
The initial letter of 'cell' is 'c'.
'tied' placed around 'c' is 'ticed'.
'en'+'ticed'='ENTICED'
(Other definitions for enticed that I've seen before include "Persuaded with attractive offer" , "Tempted, lured" , "were seductive" , "Given inducement" .)
