Forty-year-old William Coday lived the quiet life of a scholar. He spoke six languages and held degrees in history, literature, and library science. As a librarian in Fort Lauderdale, Florida, he was known to be unfailingly kind and helpful. But you can’t always judge a book by its cover…

When Coday failed to show up for work one day, a concerned colleague looked for him at his apartment…only to discover the body of Gloria Gomez. Coday’s ex-girlfriend, Gomez had been bludgeoned to death with 144 blows by two hammers and a knife. Police at the scene had little doubt that Coday was the killer. But other, darker secrets from Coday’s past had yet to come to light…

In one of the most shocking crime cases and legal appeals in Florida history, an extraordinary courtroom battle began.What the jury did not know was that Coday, when he lived abroad, had beaten another ex-girlfriend to death; the courts there had deemed him insane. Who was William Coday: Mentally unstable? Or perfectly capable—and guilty—of murder in the first degree? Soon it would be up to prosecutors to prove who the real man was BEHIND THE MASK.
