Rider Sandman -- whose reputation on the battlefields of France is exceeded only by his renown on the cricket fields of England -- returns home from war to discover his personal affairs in a shambles. Creditors have taken over his estate, leaving him penniless -- and forcing him to release the woman he loves from her obligations to marry him. Desperate to right his situation, he accepts the offer of a job investigating the claims of innocence by a painter due to hang for murder in a few days' time. The Home Secretary makes it clear that this is pro-forma, and that he expects Sandman to rubber-stamp the verdict.But Sandman's investigation reveals that something is amiss -- that there is merit to the young artist's claims. He further discovers that, though the Queen herself has ordered a reinvestigation of the circumstances, someone else does not want the truth revealed.
