John de Fairfax Look carefully at how the story began and ended. Based on many factors, I think the missing baby was actually Leofwin.
Ndf You have to read the sequel, the Butcher Bird, to find out. This was a deliberate hook into the next book in the series.
This answer contains spoilers… (view spoiler)[It can't be Leofwyn. Joan Bath specifically says he was sired by her father, thus his deformity. I think the answer may be revealed in a sequel because near the end Oswald says that more secrets are planted to be revealed later (not in those exact words). (hide spoiler)]
Anne Slater No answer-- where does the missing baby first appear? I didn't register missing baby at the beginning OR end
Patty I was hoping to find out the same thing. Did I miss something? Where is the baby? Or do we have to wait for a sequel to find out??
