The old lighthouse stood alone against the dark stormy sky. Detective Marlowe arrived at the cold scene just after midnight. Rain hammered the cobblestones as he stepped from his car. A body lay crumpled beneath the old wrought iron gate. The victim appeared to be a man in his forties. His expensive suit was soaked completely through with the rain. Marlowe bent down slowly and examined the deep wound carefully. Someone had clearly wanted this man dead very badly indeed. No wallet, no phone, and no identification of any kind. Marlowe stood and stared out at the long empty street. Whoever had done this was still somewhere out there tonight.
