He imagined the parties, the laughter, the joyous chaos that would fill the rooms. He'd even started brainstorming themes for a series of costume parties.

The detective's face did not match his mood, as she began to explain the history of the house. Roger raised a brow, a grin spreading across his face.

"A crime scene?" he chuckled. "How deliciously… dramatic!" He leaned forward, elbows on the table, eager to hear every detail. He could already envision a themed party based on the events.
