Cold October rain lashed violently against the tall study windows. Detective Arthur Vance stepped carefully over the brass threshold alone.

Vance noticed a muddy footprint near the dying fireplace embers. A faint perfume lingered beneath the sharp smell of gunpowder. The killer was definitely still hiding inside the locked mansion.
