Madame Royale, Memoirs:

One day there came [to my prison] a man who I believe was Robespierre. The officers showed him great respect. His visit was a secret even to the people in the Tower, who did not know who he was; or, at least, would not tell me: he stared insolently at me, cast his eyes on my books, and, after joining the municipal officers in a search, retired.
