9:30 a.m. to 10:45 a.m.: Farrah Rochon

Rochon gives an interactive deep dive into creating characters using various methods rooted in psychology, including characterization with the Myers-Briggs Type Indicator and Keirsey-Temperament Sorter, and how to apply them to fiction writing.

A USA Today bestselling author, Rochon hails from outside New Orleans and has garnered acclaim for her Holmes Brothers, New York Sabers, Bayou Dreams and Moments in Maplesville series. The two-time RITA Award finalist also received the Emma Award for Author of the Year in 2015

11 a.m. to 12:15 p.m.: Jean Redmann and Greg Herren

The central character in a mystery often is a detective who eventually solves the mystery by logical deduction. Through the years, Redmann and Herren have created dozens of characters in their mysteries, and they explain how to create logical, believable, complex characters that readers will love.

Redmann writes two mystery series, one featuring New Orleans private investigator Micky Knight, and as R. Jean Reid, the Nell McGraw series, about a Gulf Coast town newspaper editor. Her books have won first place in the ForeWord mystery category, as well as several Lambda Literary awards.

Herren is the author of more than 30 novels and has edited more than 20 anthologies. He has won numerous awards, including the Anthony and Lambda Literary Award (twice). His short story collection "Survivor's Guilt and Other Stories" was released on April 1, and his next novel "Royal Street Reveillon" will be released this September.

12:30 p.m. to 1:45 p.m.: O’Neil De Noux 

The evolution of the femme fatale in detective literature has a distinct development from the early days of the victim in Poe to the deadly archetype seen in the Chandler and Hammett novels and film noir. De Noux explains the archetype and how it is used today.

De Noux, of New Orleans, has 40 books published, 400 short story sales and a screenplay produced. His fiction has received the Shamus Award for Best Short Story, the Derringer Award for Best Novelette and the 2011 Police Book of the Year.

2 p.m. to 3:30 p.m.: Adrian van Young

Van Young will focus on writing, including basic methods of characterization, building unlikeable, as well as likable characters (crucial to mystery fiction and crime); and establishing narrative unreliability, which he says is important in mystery writing. He will use a combination of writing exercises and excerpts from published works.

Van Young is the author of "The Man Who Noticed Everything," a collection of stories, and "Shadows in Summerland," a novel. He received a Henfield Foundation Prize and has twice been nominated for the Pushcart Prize. He teaches creative writing at Tulane, St. Martin's Episcopal School and The New Orleans Writers Workshop.

Following the defeat of the Confederate States of America in 1865, white Southerners launched a social movement commonly referred to as the Lost Cause, which views the war as a defense of states' rights in the face of aggression rather than a defense of slavery. Marksbury will focus on the definition of The Lost Cause.
