This is a series I have enjoyed for years, this one was not my all time favorite but it was still quite enjoyable. There were at least two mysteries involved in this story: one was involving King John, the second was about a long missing Sicilian boy, and third was an unrelated mystery of a family of drapers with an illegitimacy over generations which culminated in a murder.
The Medieval Lincoln and its historical atmosphere of the series is just right, but sometimes the characters do not spring to life. Nicolaa de la Haye, hereditary castellan of Lincoln castle, and her husband Gerard de Camville, Sheriff of Lincoln always are credible, this book is no exception. Gianni could be a bit more colorful as could the Templar.
If there is another outing I will be glad to read it. Recommended for historical mystery Medieval fans.
