His relations should be interesting (11)
I believe the answer is:
storyteller
'his relations should be interesting' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for storyteller that I've seen before include "Dishonest retailer" , "Narrator (possibly a liar?)" , "Raconteur" , "novelist?" , "he retails pork pies" .)
