Then one day, Sarah makes a copy of his key. She tells herself she'll never use it... until she reads the description of a man wanted in connection with a missing woman. And she lets herself in.
Finally, she discovers everything he's been hiding. His rammed house is a time capsule of clutter.
As Sarah visits the house in secret, digging deeper through a lifetime of possessions, she comes to suspect that everything about Michael and her relationship with him is a carefully constructed lie, designed to cover his tracks and hide his true nature.
For sometimes, there's no better place for a killer to hide their trophies than in plain sight. And when Michael's key turns in the lock, there may be no escape.
