Rain hammered the glass while Detective Mara Voss entered the library and found Sir Edmund Hale dead beside his fireplace. A silver letter opener lay near his hand yet the study door stood locked from inside according to the butler. Outside thunder erased every footprint from the gravel path while inside three guests rehearsed their sorrow with careful eyes tonight. Mara noticed black ink on his cuff although no pen rested among the scattered books papers and letters near him. Then the clock struck twelve and every candle died as a whisper named the killer nobody remembered inviting inside tonight.
