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, Pete Hamill).
Foxing to the page and board edges of this hardcover, and the jacket shows some rubbing and shelfwear. Clean and neat inside, though: a good reading copy.
