The woman in the library (3)
I believe the answer is:
she
'the woman' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for she that I've seen before include "H. Rider Haggard novel" , "That woman" , "1887 Rider Haggard novel" , "Female pronoun" , "Book" .)
