A true story of murder, family betrayal, and unimaginable survival. When sisters Nikki, Sami, and Tori Knotek finally found the courage to speak out, they exposed one of the most shocking and horrifying true crimes in modern American history. For years, Shelly Knotek — their mother — inflicted unimaginable abuse on not only her daughters but also on friends and houseguests who entered her home in rural Washington State. Manipulative, cruel, and charismatic, Shelly turned their home into a house of horrors hidden in plain sight. But the girls survived. And their strength, love, and bond as sisters became the key to escaping the nightmare — and bringing their tormentor to justice. Raw, riveting, and unforgettable, If You Tell is not just a tale of murder — it’s a harrowing journey of trauma, survival, and ultimately, hope. Gregg Olsen masterfully chronicles this real-life case with compassion and unflinching truth, honoring the courage of three sisters who refused to be silenced. #If You Tell: Gregg Olsen #If You Tell: A True Story of Murder, Family Secrets, and the Unbreakable Bond of Sisterhood #Gregg Olsen
