The heavy rain pounded against the cracked pavement where the motionless body lay cold under the single flickering yellow streetlamp. Detective Miller adjusted his soaked fedora before kneeling down to examine the silver knife sticking out of the victim's chest. Dark crimson blood swirled slowly with the muddy water, creating a gruesome pattern that stained the expensive Italian leather shoes. A sudden noise from the alleyway caused Miller to turn his head toward the shadows lurking behind the rusted dumpster. He realized quickly that this calculated murder was not a simple robbery gone wrong but a message sending a warning.
