They were a picture of youth and love - and they were the essence of evil. They were married in a picture-perfect wedding in Niagara-on-the-Lake and they rode off in a horse-drawn carriage. Karla Homolka and Paul Bernardo were the very image of love and success. But they had blood - including the blood of Karla's own younger sister - on their hands. This is the definitive inside account of a serial murder case unparalleled in history. It is a story of a man and a woman joining together in torture and mutilation crimes that are virtually unspeakable. It is a story of sexual depravities videotaped by Bernardo and Homolka themselves - tapes so shocking that a trial judge ordered them destroyed, though they are rumored to have surfaced in New York and Tokyo. It is a story of authorities taking six years and twenty-three victims to stop the killings - even after Paul Bernardo's sister and best friend had both tried to turn him in. Investigative journalist Stephen Williams takes you inside this shocking case - into the motivation of a couple wed in blood, into the details of their crimes and motivations, to perhaps the worst outrage of all; the sweetheart deal that allowed Karla Homolka to escape punishment for her deeds.

Stephen Williams has spent the last three years, since the arrest of Paul Bernardo and Karla Homolka, attending their trials and researching and writing this book. He lives on a farm outside Harriston, Ontario with writer Marsha Boulton.

"Readers will leave Invisible Darkness knowing that it's nothing short of obscene.....Homolka could be out of prison as early as next year."

Ottawa Citizen

"If any readers still believe she was a victim of post-traumatic stress, abused into submission by Bernardo, this book will put that idea to rest."

Winnipeg Free Press

"Williams has performed a remarkable, if unconventional, feat in the annals of true crime."

The Toronto Star

"You may think you've heard enough but you haven't heard the half of it. It's a must read ....Based on court documents....as well as countless interviews with police, lawyers, psychiatrists and friends of Paul and Karla, it is well-researched and thought-provoking."

The Edmonton Sun

"This book lets it all hang out....You can't help but be drawn in by this tale of sex, death, lies and videotape...."

The Calgary Herald

"Invisible Darkness offers up Karla Homolka, 17 years old at the time she met Paul Bernardo, as a Devil Incarnate just waiting to meet her Svengali."
