Who is William K. Cuthrell from Welcome to the Monkey House and what is their importance?

Cuthrell is a representative of the State Department. He is sent to Virginia to investigate Barnhouse. He, like the General, would like Barnhouse to reveal the secret to his powers. Unlike the General, he is not forceful or abrasive. However, he does not take Barnhouse seriously when Barnhouse wants to use the powers for peace. He implies that Barnhouse is naïve. When Barnhouse escapes, Cuthrell seems relatively calm. He gives off the impression of a man who has worked in government long enough to have seen everything.
