April 1933. To the costermongers of Covent Garden Eddie Pettit was a gentle soul with a near-magical gift for working with horses. When Eddie is killed in a violent accident, the grieving costers are deeply skeptical about the cause of his death. Who would want to kill Eddie, and why? Maisie's search for answers begins in the working-class streets of Lambeth, but quickly leads her to a callous press baron, a 'has been' politician named Winston Churchill lingering in the hinterlands of power and, most surprisingly, to Douglas Partridge, the husband of her dearest friend, Priscilla. As Maisie uncovers lies and manipulation on a national scale, she must decide whether to risk all to see justice done.
