Book excerpt: Indiana State Police Captain Matt Leach led the hunt for John Dillinger during the violent early 1930s. Pushing a media campaign aimed at smoking out the fugitive, Leach elevated Dillinger to unprecedented notoriety. In return, Dillinger taunted him with phone calls and postcards, and vowed to kill him. Leach's use of publicity backfired, making him a pariah among his fellow policemen, and the FBI ordered his firing in 1937 for challenging their authority. This is the first full-length biography of the man.
