Murder in the Trembling Lands is the newest Benjamin January mystery by Barbara Hambly. It is Carnival time, and Ben is working asa musician at all the balls and fetes. He is therefore present when one man calls out another, accusing him of being an Octoroon instead of a white man. A duel ensues, and Ben is asked to attend as a physician.

One of the men, Corvallis, is shot. When Ben examines the body, he realizes the victim has been shot by a rifleman in the trees, not the other duelist. Moreover, the other man has recently had all his gambling debts paid off. So the murder of Corvallis was murder, and a carefully planned one as well.

Shortly thereafter, Ben is asked by his white stepbrother to search an old and abandoned plantation of something – papers or something else – by the daughter of a disgraced man who was accused of treason during the War of 1812. Ben, himself, fought in that war, primarily at the Chalmette Battlefield. In that battle, a large and professional army of British soldiers was defeated by Andrew Jackson’s hastily assembled army of volunteers, including the free blacks like Ben.

Now Ben has several tasks before the murder can be solved. He must discover what exactly happened during the War of 1812, and the battle at Chalmette. He has to help his step brother, and protect him from his foolishness. And, Ben has to accomplish all this while working, and trying to survive the men trying to kill him.

This is a rousing story with an intricate plot. But for me, the attraction is always the exotic culture of New Orleans during this time and the complication interpersonal relationships. The rules governing the whites, the free blacks, and the slaves are complicated to say the least. This is a society where the wealthy white planters choose placees, beautiful women of color, as their mistresses. Thus, it is common for the white children to have half-siblings from ‘the shady side of the street’. The white family demonstrate a variety of reactions to their darker family members, from complete acceptance to outright hatred. I certainly don’t blame the Americans, recent entries into this society, of being confused by the complex rules governing it.

Highly recommended.
