April, 1933. To the costermongers of London, Eddie Pettit is simply a gentle soul with a near-magical gift for working with horses. When he is killed in a violent accident, the costers are sceptical about the cause of his death, & recruit Maisie Dobbs to investigate. Maisie, who has known these men since childhood & remembers Eddie fondly, is eager to help. But it soon becomes clear that powerful political & financial forces are equally determined to prevent her from learning too much about Eddie's death. As Maisie uncovers lies & manipulation on a national scale, she must decide whether to risk all to see justice done.
