Hastened to get organised? (3)
I believe the answer is:
ran
I believe this clue is a double definition.
'hastened' is the first definition.
(I've seen this before)
'organised?' is the second definition.
(run can mean to organise or lead)
'to get' acts as a link.
(Other definitions for ran that I've seen before include "Went fast" , "Sped" , "at speed?" , "Directed - fled" , "Took a single" .)
