The entire day had been a whirlwind of activity, and he reveled in every second. He’d bounced between errands, humming a ridiculous made-up tune that sounded like a cross between a marching band and a polka. Each task was just a step closer to the ultimate goal. He whistled as he unlocked the door, his heart thrumming with excitement.

The apartment was dark. He flipped the light switch, but nothing happened. He called out, “Hello?” Silence. His grin faltered as he noticed a single envelope on the table. Inside, a hastily scribbled note informed him the plan had changed. His stomach dropped. The whistling died in his throat.
