The night whispered dark secrets. Fog rolled through quiet streets. Cold rain fell like tears. Detective Morgan checked her watch. Two bodies found by midnight. Blood stained the marble floor. Broken glass reflected the moonlight. Someone locked all the doors. The mansion held deadly truths. Family portraits watched in silence. Rich people keep dangerous secrets. Each suspect had strong motives. Money always complicates simple matters. Inheritance brings out the worst. The patriarch died too suddenly. His will changed last week. The butler discovered the bodies. Someone wielded the silver knife. Fingerprints were wiped too carefully. The detective sensed hidden eyes. This case promised many twists.
