A comic "Mr," possibly stalked (4)
I believe the answer is:
bean
'a comic' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bean that I've seen before include "Haricot or runner?" , "Pulse" , "popular character with kids" , "It's often baked" , "Edible seed" .)
