The Excalibur Murders

Merlin makes a great investigator – and it only looks like magic. Merlin is no magician, merely a scholar and advisor to King Arthur. But after the supposedly magical Stone of Bran is stolen – along with the legendary sword Excalibur – and one of Arthur's squires is brutally murdered during the theft, Merlin must use the power of reason to conjure up a miracle and catch a murderer.
