The bestselling author and true crime master Ann Rule presents her fifteenth volume of the acclaimed Crime Files series focusing on disturbing stories of people in danger,.

Walking home on a dark night, you hear footsteps coming up behind you. As they get closer, your heart pounds harder. Is it a dangerous stranger or someone you know and trust? The answer is as simple as turning around, but don’t look behind you…run.

With her signature in-depth research and compelling writing, Ann Rule chronicles fateful encounters with the secret predators hiding in plain sight. First in line is a stunning case that spanned thirty years and took one determined detective to four states—ending, finally, in Alaska—where he unraveled not one but two murders. A second case appears to begin and end with the hunt for the Green River Killer, focusing on a Washington State man who was once cleared as a suspect in that deadly chain of homicides. In another true story, a petite woman went to a tavern, looking only for conversation and fun. Instead, she met violent death in the form of a seven-foot tall man who had seemed shy and harmless.

You’ll feel a chill as you uncover these and numerous other cases of unfortunate victims who made one tragic mistake: trusting the wrong person—even someone they thought they knew.
