Praised by Library Journal as 'an encouraging debut,' the paperback edition of this gripping historical thriller is the first of Sir Roger novels where he is unexpectedly summoned by Prime
Minister Gladstone to investigate a gunpowder-plot. As the novel progresses towards it dramatic and unusual climax, Roger finds strange similarities to an earlier, unsolved case and discovers
that the clue to this mystery is connected to none other than a man whom Roger knows very well. Original.
