Synopsis:
A Jonathan Gray, M.D. Mystery
On a frosty Sunday morning in February, Dr. Jonathan Gray, Coroner of Orleans Parish, faces a gruesome sight. A dead man splayed against the circular steel and cut-glass blocks of the city’s AIDS memorial in Washington Square Park has strange symbols carved into his forehead and chest. A coded note—a cipher—has been placed under one hand. The body mutilation and note are hallmarks of a serial killer dubbed by the news media as the “Mardi Gras Sweeper,” because he strikes during Carnival season and leaves coded manifestos taunting police and giving hints about his next victim.
Hoping to avoid a panic during the city’s most profitable season, Mayor Max Jamerson asks Gray to investigate the murder “on the sly,” without formal assistance from the New Orleans Police Department. Time is of the essence as Gray races to figure out the cipher and track down the Sweeper in order to prevent additional killings—and save Mardi Gras.
Praise for Shadows of Frenchmen:
"A chilling, razor-sharp mystery set against the explosive energy of Mardi Gras. This cat-and-mouse hunt fuses cryptic clues, relentless suspense and rising terror into a tale that gives us a horrifyingly intimate glimpse into a killer’s mind. Dr. Jonathan Gray is a hero you won’t forget—and the Mardi Gras Sweeper is a nightmare you won’t escape."
~ Kathleen Antrim, Bestselling Author, President-Outliers Writing University

Chapter One
Alpha and Omega
Sunday, February 1, 2015 – 1:47 a.m.
Twenty-plus years with the Orleans Parish Coroner’s Office taught Jonathan Gray to expect the unexpected. But Washington Square Park had always been a tranquil haven on the fringe of the French Quarter. So crime-scene tape draping the square’s wrought-iron fence presented the visual equivalent of fingernails on a chalkboard. Moonlight filtering through stately live oaks cast eerie—almost funereal—shadows, adding to the dissonance.
Fluttering in the nippy midwinter breeze, the neon-yellow ribbon communicated
a mute warning. On this side, normalcy. On the other, insanity. Stepping into the dysfunction never got easier. Regardless, turning back wasn’t an option. As if speaking the incantation aloud would immunize him against the unfolding drama, he repeated his trite pre-crime scene mantra: “Abandon all hope, ye who enter here.” His breath lingered in the frosty air before evaporating.
After checking in with the uniformed officer monitoring access, Jonathan angled toward floodlights illuminating a temporary canopy above the city’s AIDS memorial. More tape—red as opposed to yellow—identified the innermost “Do Not Cross” perimeter. Crime scene technicians in white Tyvek protective suits busied themselves measuring and photographing what must be the reason he’d been summoned. A male corpse sitting upright on the ground—its arms and legs twisted at seemingly impossible angles—leaned against the memorial’s circular cut-glass and steel panels surrounded by a pool of thick, dark-crimson liquid.
A curved, nearly rectangular piece of wood with brass edges—most likely a knife handle—protruded from under the right side of the dead man’s rib cage. A portion of his intestines spilled out of the wound. A second knife—its handle and part of its blade visible—had been thrust downward into the soft tissue between the left collarbone and neck.
Cause of death seemed too obvious to require someone of Jonathan’s seniority. A first-year med student could have made the call. But markings carved into the dead man’s forehead and chest hinted at something more sinister. No wonder Mitch Broussard from NOPD had called him in the middle of the night. The man’s heavy flannel shirt lay open, exposing his chest and a series of
capital letters etched into his skin. The letters—G I D I A I D I V—made no sense, at least not in English. A folded piece of paper with similar letters and other symbols, not quite readable from that distance, lay under the man’s left hand. Lack of blood covering the letters in the chest signaled they had been added postmortem. Jonathan focused on two marks in the man’s forehead. An uppercase “A” and what looked like an upside-down horseshoe—the Greek letter Omega—apparently cut while the victim was still alive.
It couldn’t have been two years already. But there it was. Alpha and Omega. Jonathan bit his lip and cursed under his breath. Then, a silent prayer. Looked like the nightmare was about to begin—again.
One of the CSTs stood and raised her clear face shield. “Hey, Doc. Welcome to Funsville.”

Review:
As Mardi Gras rolls on, a killer stalks the streets of New Orleans.
Shadows of Frenchmen is the second book in author Michael Rigg’s atmospheric Jonathan Gray, M.D. Mystery series, and this time a killer stalks the streets as the city gears up for its fabled Mardi Gras festivities. Only weeks after replacing his deceased mentor and friend as the Coroner for Orleans Parish, Dr. Jonathan Gray, M.D. faces a new challenge when called to the scene of an enigmatic murder. It has all the markings that a serial killer, the Mardi Gras Sweeper, has returned on his murderous biennial killing spree; however, it was believed that he’d been killed when he fell to his death into the Mississippi River two years earlier. Hobbled by the mayor’s restrictions to keep this new murder under wraps and out of the media and short-staffed at the Coroner’s Office, Gray cuts a deal to bring in suspended NOPD Detective Lieutenant Betsy Sprance. Together, his new team works to decode a cipher left behind at the murder scene and stop the killer before he strikes again.
What a fast-paced and action-packed story! I was well and truly hooked from the start by the engaging Dr. Gray and the first shocking crime scene. Gray, still trying to get his footing as the new coroner after the death of his former boss, doesn’t let on to anyone how difficult his transition from deputy to chief has been. In his mid-50s, there are plenty of people throwing shade that he’s past his prime to take on the job. Also, personality issues between some of his staff members aren’t making things any easier.
The New Orleans setting is wonderful with numerous mentions of iconic locations and streets, familiar libations and treats, and the activities of Mardi Gras. I enjoyed the inside peek at preparations for the parades and krewes. There’s nowhere else like this city, and readers are treated to a close-up, personal armchair visit as the action and investigation quickly escalate. Nothing is as it seems, with scenes that had me confounded about what was really going on and what was really at stake, and plot twists that definitely surprised.
I recommend SHADOWS OF FRENCHMEN to readers of mysteries,
especially those who would enjoy the New Orleans during Mardi Gras setting.
