The Hundred Years' War, which had subsided, will flare up with renewed vigor any day now. English Aquitaine can come under the French crown at any time. The British diplomatic mission failed, their envoy was killed. Geoffrey Chaucer, poet and diplomat, sets out on a dangerous journey to do what his predecessor failed to do - prevent the powerful Count of Aquitaine de Guyan from swearing allegiance to the French king. When Chaucer is already at his goal, the earl dies while hunting, and his killer is not a boar, but a man. But who? It’s not easy for Chaucer to conduct his own investigation - there are ill-wishers all around, secret informants, everyone is ready to help, but you can’t trust anyone.
