How is Segretti described?

From the text:

Segretti was dressed in corduroy jeans and Scandinavian sweater and had a grin on his face when they arrived. He shook hands with Bernstein warmly. “How’ve you been?” he asked. Bernstein was struck by the fact that he was only about five foot four. This was the master spy? Secret agent with a White House badge? Segretti had a baby face, a slightly toothy smile and traces of a cowlick.
