Chapter 7 - The Hidden Safe in the StudyTwo days later, the house on Elm Street looked like a crime scene because it was one.

Yellow police tape crisscrossed the front porch. Inside, forensic technicians in white hazmat suits dusted every surface for fingerprints and boxed up Marlene’s personal belongings.
Detective Vance and I stood in Marlene’s private study—a room she always kept locked, claiming it was her "sanctuary for grading papers."
"The search warrant covered the entire property," Vance said, shining a heavy-duty flashlight behind a massive wooden bookshelf filled with leather-bound encyclopedias. "According to the financial records we pulled from her offshore accounts yesterday, Marlene didn't just inherit two million from Sarah's death. She liquidated three other life insurance policies belonging to distant relatives who died 'mysteriously' in nursing homes over the last fifteen years."
"She was a serial killer operating in plain sight," I said, running a hand through my hair, still exhausted from sleeping in the hospital chair beside Clara. "How did no one ever catch her?"
"Because people trust sweet old grandmothers who bake apple pie and judge your table manners," Vance said grimly. "Evil doesn't look like a monster, Ethan. It looks like family."
Suddenly, Vance’s flashlight beam caught a small, brass-plated keyhole half-hidden behind the baseboard molding.
"Hold the light," I said, dropping to my knees.
I reached into my pocket and pulled out the small, ornate key I had found tucked inside the lining of Marlene’s leather purse on the day this nightmare started—the one she thought was just a house key.
I slid it into the brass keyhole.

The entire bookshelf swung inward with a heavy, oiled groan, revealing a hidden room no one in the family had ever known existed.
