By Noel Behn. Behn's take appears to be on the crackpottier "Hauptmann was innocent" side of things, but the tie-in to then-governor Harold Hoffman's doubts is interesting, and Lord knows Behn got some heavy-hitting blurbs (Gay Talese).
Mild edgewear to this paperback, and a crack in the spine, but sits very straight; a fine reading copy.
