Charles Stafford

 was a professor who was interested in what Bernice Summerfield had found out when she went to Canatha. He tried to help Benny regain her memory. He bribed her to go Canatha, with a rare book, a mnemosine store book. He tied her to a chair so that he could get the information he wanted from her. (PROSE: A la Recherche du Temps Perdu)
