But nobody knows how frightened I am at night. Oliver promises he’ll keep me safe, but I can’t stop feeling like someone from my past is watching me. Coming for me. I could have sworn I saw someone watching me through the window, lurking in the shadows across the street.

It was supposed to be a fun weekend at our family cabin. I was going to surprise my husband, Mike, with a small get-together for his 40th birthday. Something is wrong, though.

It’s what we need for us. When I get to the cabin and set up, I hear sounds coming from the basement. That’s when I see her. A young woman tied up and scared.

Callie was living in a ten-acre home in the stunning Adirondacks with her husband. She missed her son, who was away at college, but she was coping pretty well with her empty nest. Then, the nightmare began. Her husband Abel skidded off the road into an icy lake. His truck hit a tree and plunged into the frigid water below.

The police say it was an accident, but the details remain murky.

Mark and I pride ourselves on giving visitors to our hotel, high on the rugged Maine cliffs with views of the ocean, a vacation they won’t forget.

"There’s someone I want you to meet," Belle says, as a man draws up to her side. He’s tall with dark hair and stubble on his square jaw. He’s not exactly smiling, but the corner of his mouth curls upwards as he slides his hand around my daughter’s waist.

All marriages have their challenges, right? But as I watch my husband being put into the back of a cop car, I find myself wondering if I ever knew him at all.
