I've been aware of Brett Halliday's Mike Shayne series for a long time, and have been collecting quite a few of the books, particularly those with McGinnis covers. Like so many collectors, it's hard for me to find the time to read everything I buy, and I haven't hit the Shaynes yet, with the exception of three tales from Mike Shayne Mystery Magazine penned by James Reasoner under the Halliday name in the early 1980s. These were The Black Lotus, Death from the Sky, and Doomsday Island, and feature a female descendant of Dr. Fu Manchu (the connection is strongly implied, not explicit, due to copyright reasons).
I discuss these stories in my essay "Who's Going to Take Over the World
When I'm Gone? (A Look at the Genealogies of Wold Newton Family
Super-Villains and Their Nemeses)" in my MYTHS FOR THE MODERN AGE: PHILIP JOSÉ FARMER’S WOLD NEWTON UNIVERSE, as well as my CROSSOVERS: A Secret Chronology of the World 1 & 2.
In any event, I had always thought Shayne was strictly Miami-based, and had no recollection that he also worked in New Orleans (although I do see that my friend and colleague Brad Mengel mentioned Shayne's New Orleans sojourn in his essay "The Land Family," which incorporated Shayne into the wider Wold Newton Family).

Why a Mike Shayne paperback in Kitchen Witch Cookbooks? It turns out these cases take place during a few years while Shayne was based in New Orleans. In fact, on the back cover is a nifty map of the French Quarter highlighting the key locations of the cases.
Needless to say, I grabbed it, and had a ball reading it on vacation.
We had a great time in NOLA, and plan on return vacations. I can't think of any place that beats the French Quarter at night for atmosphere and exquisite food, and I don't mean just on Bourbon Street. In addition, my great-great-grandmother and great-great-great-grandfather were from New Orleans, and next trip I intend to track down the family mausoleum, if it still exists.

All in all, a great trip.
P.S. Consider these your "pics o' the day." Now that I'm back from vacation, I'll try to resume the daily pics soon.
