AS WE DROVE BACK toward the department, a rainstorm swept across the wetlands and pounded the cruiser and scattered hailstones like pieces of smoking dry ice on the road. Back at the office, I began the paperwork on the death of Yvonne Darbonne. I had completely forgotten the matter of the dye-marked one-hundred bills in the possession of Trish Klein, the daughter of my murdered gambling friend in Miami. Just before quitting time, Helen opened my door. “We got a hit on those serial numbers,” she said. “The bills came from the robbery of a savings and loan company in Mobile.”

Helen’s announcement wasn’t what I wanted to hear. “I’ll get ahold of the woman tomorrow,” I said.

“It gets better. The bills from the robbery have been showing up in casinos and at racetracks all along the Gulf Coast,” she said.

“The Klein woman says she got hers at a casino in Biloxi.”

“Here’s an interesting footnote. The Treasury guys think the savings and loan company may be a laundry for the Mob. The wiseguys got ripped off by some bank thieves who didn’t get the word. What’s the background on this Klein woman?”

I told her about the shotgun slaying of Dallas Klein in Opa-Locka, Florida, years ago. Through my second-story window I could see rain hitting on the tops of the crypts in St. Peter’s Cemetery.

“You were there when he died?” she said.

“Yeah,” I said, my voice catching slightly.

“Wrap up our end on this and give it to the Feds. You copy on that?”

“Absolutely,” I replied.

I DROVE HOME at 5 p.m. and parked my pickup truck under the porte cochere attached to the shotgun house where Molly and I live in what is called the historical district of New Iberia. Our home is a modest one compared to the Victorian and antebellum structures that define most of East Main, but nonetheless it is a beautiful old place, built of cypress and oak, long and square in shape, like a boxcar, with high ceilings and windows, a small gallery and peaked tin roof, and ventilated green shutters that you can latch over the glass during hurricane season.
