The Sinister Secret of Saltmarsh (U1) TSR# 9062

From the title page: Desolate and abandoned, the evil alchemist's mansion stands alone on the cliff, looking out towards the sea. Mysterious lights and ghostly hauntings have kept away the people of Saltmarsh, despite rumors of a fabulous forgotten treasure. What is it's sinister secret? The Sinister Secret of Saltmarsh is the first installment in a series of three modules designed and developed in the United Kingdom, for beginning adventurers with the AD&D(TM) rules. The adventure can be played by 5-10 characters of level 1-3. This module contains large-scale maps, full background information and detailed encounter descriptions for the players and DM. The module is divided into two parts, The Haunted House and Sea Ghost, which are intended to be played consecutively. The first part is set in the town of Saltmarsh and deals with unraveling the secret of the haunted house that lies on the edge of town. The abandoned, dilapidated mansion of an evil alchemist has been the subject of rumors about hauntings and treasure. The second part of the module follows on from the first, expanding on the concept.
