April 1219: Edwin Weaver finds himself at Tickhill Castle under false pretences. Earl Warenne wants Tickhill for himself and is convinced that a royal order for the castle to be handed over has been hidden, so he’s sent Edwin to find it and told him not to come back until he does. Frantic with worry about the danger to his family, Edwin is forced to lie to everyone around him while searching for a document that might not even exist.

The situation escalates when a body is found and the earl musters armed troops to take the castle by force; Edwin must race against time to discover the crucial information so he can stop the violence and bloodshed. But his quest for the truth is more dangerous than he could possibly have anticipated, and he must endure tragic and wrenching loss before his duty is complete.
