Rain hammered the harbor while Mara Venn found the senator dead beside his cold breakfast and a fresh black orchid. The windows were locked from inside and every clock within the study had stopped at eleven minutes past midnight exactly. Detective Ilya Crowe noted sapphire cufflinks scattered near the curtains and lipstick blooming across the crystal glass like dark blood. A maid swore she heard arguing below the stairs then silence then a shot muffled by thunder over the bay. By dawn the guests waited in the green salon holding their secrets tighter than the pearl handled knives beside them.
