Was bound to be taken in (3)
I believe the answer is:
had
'be taken in' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for had that I've seen before include "Was bound to be - caught" , "Did trick" , "kept" , "Taken in" , "Was in possession of" .)
