Merlin’s adventures continue next Saturday with the eighth episode of 13, Lamia.

A mysterious illness draws Merlin to a distant village. But it soon becomes clear that there is more at stake than just his well-being as something sinister turns the air sour. Far from home and with no one to trust, Merlin becomes embroiled in a deadly game of cat and mouse. No longer sure who is the hunter and who is the hunted, can the young warlock survive long enough to uncover the truth?
