The rain fell hard on empty streets that cold night. The detective stood beneath the flickering streetlamp watching the darkness. A woman's scream pierced through the wet evening air suddenly. Nobody else was around to hear what would happen next. Inspector Mara knelt beside the body on cold wet pavement. Her white gloves were stained with something dark and sticky. The victim wore a red dress and expensive diamond jewelry. A white rose lay crushed near her cold outstretched hand. Mara noticed the missing engagement ring on her left finger. Someone had killed her for love or perhaps for money.
