In 1141, two monks have arrived in Shrewsbury from Winchester, where their abbey was destroyed. Now Brother Humilis, who is very ill, and Brother Fidelis, who is mute, must seek refuge at Shrewsbury. And from the moment he meets them, Brother Cadfael senses something deeper than their common vows binds these two brothers.
