The first scream echoed through the grand ballroom at precisely midnight. Detective Miles arrived to find the guests huddled together fearfully. He approached the body lying beside the shattered champagne flute. A single, perfect crimson rose was pinned upon her chest. There was no murder weapon found anywhere at the scene. Every single guest claimed they saw absolutely nothing at all. But one of these eleven elegant people was lying. Miles knew he would have to uncover their secret. The truth always hid behind the most polished facade.
