Lightning flashed violently across the sky, momentarily illuminating the old Victorian mansion at the end of Hawthorne Street. Thunder rolled ominously, as Inspector Lydia Grant pulled her coat tighter against the chilling winds of the night. A call had summoned her urgently: something terrible had happened, details vague, an atmosphere tense. Stepping inside, the air shifted palpably, thick with mystery and faint whispers of the past echoing through grand halls. In the grandioom, an array of guests stood, draped in black, their faces etched with fear and confusion. There, lying cold on the Persian rug, was Sir Jonathan Blackwood, esteemed billionaire and collector of rare artifacts. Lydia noted the room's delicate tension, the careful distance everyone maintained from the body, eyes darting suspiciously. Tonight, in this shadow-laden house filled with secrets, Lydia knew her skills would be tested to their very limits.
