Gino Marchal (Belgium)
Gino Marchal is the co-author of The Fourteenth Letter with Mac De Bel. An R&D engineer by day and an amateur-sleuth by night. After an intense investigation last year, he believes to have solved the largest art puzzle in Belgium's history: the location of stolen painting by Van Eyck. He likes to solve puzzles, find his way out of an escape-room, or engage in some mad-scientist tinkering when he's not playing with his cat Igor.
