Book excerpt: The father of Eric Edgar Cooke despised his baby son from the moment he saw him. Bashings and a hate-filled childhood followed for the boy with the crooked mouth, launching a personality unique among serial killers. He stalked the city of Perth for months, shooting strangers in the dead of night and using a sickening variety of weapons to steal the lives of strangers. Unknown to the terror-stricken citizens of this trusting, emerging metropolis, the young father of seven children who pulled the trigger had for years been doing other sinister night work. In a remarkable twist of fate, the killer's life tangled with that of 19-year-old John Button, whose 17-year-old girlfriend was killed. Both men confessed to that crime. This riveting investigation into the life and untold crimes of the last man to hang in Western Australia reveals new evidence to indicate that at least one innocent man, John Button, went to jail for one of Cooke's murders. Estelle's efforts to clear John Button's name, have led to the West Australian Court of Criminal Appeal re-opening the case against John Button after nearly 35 years. The new edition will include a chapter covering the case and the final decision.
