Told the next of kin (7)
I believe the answer is:
related
This could be a double definition.
'told' is the first definition.
(as in relating a story)
'next of kin' is the second definition.
'related' can be an answer for 'kin' (I've seen this before). I am not certain of the 'next of' bit.
'the' is the link.
Can you help me to learn more?
(Other definitions for related that I've seen before include "Told; akin" , "Agnate" , "Father and son have to be" , "Having family links" , "were sympathetic" .)
