Twelfth Knight: A Christmastide Tale

Sir James and his lovely wife, Lady Elena, now married and both serving as Garter knights for King Henry VII, find themselves back in Warwickshire for the Christmastide celebration.

Lady Elena is heavy with child, but that doesn't stop her from carrying out her duties--though James would prefer for his wife to rest until their baby is born.

But on the Twelfth Night, the king's son goes missing after Elena has been named his protector.

Is it just a Christmastide prank, or are darker forces moving against the king and the Garter knights?
