Something seems off. Lupin sensed it before it happened. When a simple burglary goes terribly wrong, and two of Lupin's accomplices are sentenced to the guillotine, Lupin's quest to free them reveals itself to be more twisted and darker than he'd ever imagined.

Inspired by the infamous Panama scandals of 1892 and 1893, and expanding on the main concept in Poe's The Purloined Letter, Leblanc weaves a thrilling tale of twists and turns with Lupin's characteristic panache.
