The scariest crime is the one you never see coming. You are most likely to be murdered by someone you know and would never do you harm... or so you thought. Even with the people you trust the most, there may be something sinister lying beneath the surface - a calculated plot set in motion by someone close with a deadly motive. Someone You Thought You Knew tells the stories of murders that were orchestrated by a master manipulator, scheming right under everyone's noses. These wolves in sheep's clothing use deception as a weapon to try to get away with murder. The victims are killed by people they loved, trusted and thought they knew... but really didn't know them at all.
