Question about a version of "The Baby Roast"

[UrbanTruth 1]

I'm already familiar with the version involving the hippie babysitter getting high and accidentally roasting the baby while it's parents are out for the night. However I came across another version that I found to be more interesting and far more chilling.

I found it from "The Encyclopedia of Urban Legends" by Jan Harold Brunvand.

Apparently it originated from Argentina, and goes like this:

"A young couple hires a young nanny since the wife is pregnant and almost due. The baby is born. A few weeks later the husband and wife go to the movies one evening, leaving the baby in the nanny's care. Until that time, she has always been reliable. When the couple returns, she approaches them ceremoniously dressed in the wife's bridal gown and tells them that she prepared quite a surprise for them. She leads them into the dining room to serve them a special meal. They enter and find a horrifying spectacle. In the middle of the table, placed there with great care, they see thier son on a large platter, roasted and garnished with potatoes. The poor mother goes insane at once, literally losing her speech. The father, who is a military man, pulls out a revolver and shoots the nanny to death, then runs away and is never seen again."

As you can see, that version is pretty summarized. I'm very interested in that version and want to know more about it. To those who are avid readers of Jan Harold Brunvand's books, and are aware of this particular version of the legend, which of his books, or books in general, have that specific version of the legend told in more lengthy detail?

Read the Norse Sagas or the Greek myths.    There are several versions of wives revenging themselves on their kingly husbands by murdering and serving their children. Also Weyland the  Smith, the English name, but his story also extends into past Scandinavian and Germanic times.

Never p*** off a queenly wife or try to cripple a legendary smith.
