Octavus Roy Cohen,
Jim Hanvey, Detective — The Knight's Gambit
(1923)
“ Hanvey expressionless as ever, Kirk struggling to conceal the worry inspired by Jim's air of confidence. Whitey knew that he had never slipped in his decade of criminality—he knew but he wasn’t sure. Perhaps, somewhere in that period, there had been an error of judgment, a weakness which he did not suspect. He knew the axiom of the criminal world—a detective may make a thousand mistakes and yet be successful; a criminal cannot err once. Warren Kirk realized that he was only human—and therefore fallible. ”
