In December of 1718, the two surviving members of the crew of notorious pirate Stede Bonnet (all the others having been hanged along with him in colonial Charles Town, South Carolina) made their way up the Ashley River. Under the cover of darkness and using a mixture of oar and sail, they made their way to Fort Dorchester bringing a cargo of contraband silks and linens for delivery to Joshua Bailey, plantation owner and warehouseman. A mysterious box was also part of the cargo to be delivered but never mentioned by any of the parties other than to answer the question presented by a slave named Jamaica, “Do you have it?’
Three hundred years later some books belonging to the planter Joshua Bailey are stolen from the rare book room of a subscription library in Morgan, South Carolina. One of the suspected thieves is attacked and found near death in the marsh on the edge of an exclusive neighborhood in Morgan. Upon the death of the first man another murder occurs, as the investigation begins to focus on something that occurred 300 years earlier.
The story of December Rain is told in alternating chapters between the current day investigation and the life history of the Nichols family (the youngest of the two seamen making the delivery to Joshua Bailey). Weaving through centuries of historic data from King Georges War through the Civil War, Sidney Lake is asked to help research the connections between the Bailey family and current day, while Tillie James explores oral histories in the Gullah community that date back to Joshua Bailey’s slave holdings. Thus begins a wild ride through history that uncovers a genealogical line no one anticipated.
