Rain pooled black on the cobblestones while Inspector Mara Voss counted the house lights and found one window deliberately dark. The gate stood open though the lock was bright with new scratches and the bell had been muffled by wool. Inside the parlor smelled of bitter almonds pipe smoke and lavender polish laid thick enough to hide a fresher stain. A clock faced the wall hands stopped at eleven forty seven beside a cup gone cold and a chair overturned. Mara touched nothing because the dead man on the rug was smiling toward the stairs where someone had wiped footprints. Then the telephone rang once stopped and rang again as if the caller knew she had just looked toward it.
