Marion Grey is growing used to the idea that her husband will never leave prison. After the horrors of a very public trial she's almost able to find relief in her resignation. But when new evidence suggests her husband may be innocent after all, she hires a professional-Miss Maud Silver-to clear his name. It begins with a chance encounter on a busy train, when a friend of Marion's meets a half-mad woman who claims to know something of the Grey case. With her is a man who disappeared during the trial-and may have information that could set Marion's husband free. But who is he, and where has he gone? To find out, demure governess-turned-detective Miss Silver must track him down before becoming a victim herself. In a series that's a delightful blend of Downton Abbey and Agatha Christie, retired schoolteacher and sleuth Miss Silver "has her place in detective fiction as surely as Lord Peter Wimsey or Hercule Poirot" (Manchester Evening News).
