The Silent Man: The Abbey Mysteries: v.2 by Cherith Baldry
When Lord Ralph's young daughter goes missing in the village, the gentle mute Bedwyn is arrested for murder and thrown into the Abbey dungeons. Gwyneth and Hereward refuse to believe that this shy man could be responsible for such a despicible crime and set about trying to prove his innocence. While Bedwyn languishes in prison, the girl's father receives a ransom note - his daughter is alive after all. But part of the ransom is that he mustn't tell anyone. How can Hereward and Gwyneth persuade Lord Ralph to speak up, so Bedwyn will be released? This book is being published in partnership with the successful packaging company, Working Partners, who are responsible for such series as "Animal Ark" and "Dolphin Diaries".
