The heavy rain fell steadily on the cobblestone streets, washing away the footprints of anyone who dared to walk there. Detective Sarah Chen pulled her coat tighter and stared up at the looming silhouette of Blackwood Manor on the hill. Inside those ancient walls, a wealthy industrialist lay dead in his study, poisoned by something rare and utterly without scent. The housekeeper had found the body at midnight, her screams still echoing in the minds of everyone gathered outside now. Six guests had been staying at the manor that weekend, and every single one of them had a secret motive. Sarah climbed the stone steps slowly, her boots clicking against the wet granite, her flashlight cutting through the darkness ahead. The front door stood slightly ajar, which was strange, because the housekeeper swore she had locked it quite securely earlier. Somewhere inside this house of secrets, a killer was waiting, and Sarah knew that tonight would change everything forever now.
