Another interview revealed that ever since childhood she had been very suspicious of strangers.

(From Longman Dictionary.)

Does the use of the past perfect "had been" in the sentence above mean that "she" died?


No (it doesn't preclude it either). The past perfect is used because "been very suspicious of strangers" happened before (and up to) the interview, which was itself in the past. The past perfect is backshifted from a presumed present perfect in the interview itself.


Thank you for the reply.
