The Burren's Brehon (and new wife of King Turlough) Mara is faced with yet another perplexing murder when two strangers, who arrived from the Aran Islands to claim kinship with a local noble, Ardal, are found dead outside the cave of Balor. Doubts exist about the kinship but suspicion still focuses on Ardal. Was he afraid of these interlopers enough to kill them? Or is the secret deeper than that? Slowed by her pregnancy and by other problems arising in the community, it takes Mara a while to arrive at the truth.
Though I did enjoy this book, I found it slightly irritating that the answer to the solution was obvious from the beginning but the story was stretched out with the excuse of Mara's pregnancy. However, the plot was kept interesting enough to keep me reading and I did enjoy the idea of a strong female leader existing in medieval Ireland. I also enjoyed the excerpts of Brehon law that Harrison includes at the beginning of each chapter, especially this one:
"Cain Lanamna (Law of Marriage): A woman has a right to bear a child and she may divorce her husband if any failing on his part impedes that right. Divorce may be obtained if the husband is impotent, too fat for intercourse, if he spurns the marriage bed... [or] if he is sterile (and his wife has been fruitful in an earlier marriage.) In the case of sterility, if the husband wishes to retain he wife, she has the right to conceive a child with another man and then to return to her husband. The child must be reared by the husband with all rights and privileges as if it were his own. "
