"In the east end of London, a group of religious fanatics plots rebellion. In the midst of all this, a stonemason uncovers a perfectly preserved body dressed in the robes of a Dominican friar, bricked up in a wall in the crumbling Black Friars. Ill-informed rumours and speculation abound, but Seeker instantly recognises the dead man. What he must discover is why he met such a hideous end, and what his connection was to the children who have started to disappear from around the city. Unravelling these mysteries is challenging enough, and made still harder by the activities of dissenters at home, Royalist plotters abroad and individuals who are not what they seem"--Provided by publisher.
