An invisible message from a dead man resurrects a decades-old mystery. With her sharpened magical senses, Sylvia recognizes invisible writing while cataloging an obscure book for the library. She's shocked to discover the message, written many years earlier, pleaded for help. She's even more shocked to discover the author of the message was married to a paper magician. Could there be a connection to Sylvia's father? With a magical mystery on her hands, Sylvia engages the help of Gabe Glass, and together they follow the clues to the location of two hidden ledgers that implicate a very dangerous individual in an illegal bookmaking scheme. Although not named, Gabe is convinced he knows who the bookmaker is, and sets out to prove it. The investigation draws them into the shady underbelly of the horseracing industry and uncovers a link to Gabe's parents that takes everyone by surprise. As they unravel the mystery's tangled threads, unexpected twists and turns lead them to the truth. But the greatest twist of all is the danger no one saw coming.
