I Am the Cheese-Identity of Brint

Ok, this is for people who have read the book “I Am the Cheese”, by Robert Cormier. This has been bugging me ever since my Language Arts teacher introduced the topic to me in 8th grade.

In the novel, is the interrogator charecter “Brint” really the charecter of “Mr. Grey,” or Agennt #2222? If anybody has some insights as to this, i would really appriciate it.
