When a priceless collection of scores by English composer Sir Edward Elgar goes missing from a Soho crime lord’s private vault, professional musician and amateur sleuth Jason Davey is tasked to get it back. With the help of a series of clues seemingly lifted from Elgar’s own Enigma Variations, Jason sets out to track down both the thief and the collection. The chase leads him from London to Derbyshire and then back to London again, and ultimately to a heartbreaking discovery in a long-abandoned recording studio in the heart of Soho’s Tin Pan Alley, Denmark Street.
