From the introduction:
A merchant fleet, consisting of the prize ship Beleaguerer along with the Chancellor and Zephyr, is long overdue in returning to Skiff. Approximately three weeks after the scheduled arrival time, a merchant ship captained by Red Lambert reaches Skiff and has a sailor from the Beleaguerer. News travels quickly through town about the loss of the prize ship.
