One night he found me at a table by myself at Provost's and sat down without being asked, a white bowl of okra gumbo in his hands. A veterinarian and a grocery store owner I had been drinking with came out of the men's room and glanced at the table, then went to the bar and ordered beer there and drank with their backs to us.

"Being a cop is a trade-off, isn't it?" Vachel said. "Sir?" I said.

"You don't have to call me 'sir'… You spend a lot of time alone?"

"Not so much."

"I think it goes with the job. I was a state trooper once." His eyes, which were as gray as his starched shirt, drifted to the shot glass in front of me and the rings my beer mug had left on the tabletop. "A drinking man goes home to a lot of echoes. The way a stone sounds in a dry well. No offense meant, Mr. Robicheaux. Can I buy you a round?"

The acreage next to Vachel Carmouche was owned by the Labiche family, descendants of what had been known as free people of color before the Civil War. The patriarch of the family had been a French-educated mulatto named Jubal Labiche who owned a brick factory on the bayou south of New Iberia. He both owned and rented slaves and worked them unmercifully and supplied much of the brick for the homes of his fellow slave owners up and down the Teche.

The columned house he built south of the St. Martin Parish line did not contain the Italian marble or Spanish ironwork of the sugar growers whose wealth was far greater than his own and whose way of life he sought to emulate. But he planted live oaks along the drives and hung his balconies and veranda with flowers; his slaves kept his pecan and peach orchards and produce fields broom-sweep clean. Although he was not invited into the homes of whites, they respected him as a businessman and taskmaster and treated him with courtesy on the street. That was almost enough for Jubal Labiche. Almost. He sent his children North to be educated, in hopes they would marry up, across the color line, that the high-yellow stain that limited his ambition would eventually bleach out of the Labiche family's skin.
