Master thief Justin Vincent and his computer hacker partner Ashna help people recover stolen items when the authorities can't. This time, their client needs his missing research notes back—notes that could help provide the solution to a century old musical mystery. The trail is cold, but the motive is clear: a £1 million reward offered to anyone who can decode the secret message hidden in Sir Edward Elgar's Enigma Variations. Justin and Ashna come up against a mystery steeped in arcane lore lurking behind what they thought was a simple case of theft and a shadowy foe who seems to be a step ahead of them at every turn. Will they be able to identify the thief and retrieve the formula before its dark forces are unleashed on an unsuspecting world?
