The new accusation brought by Urban against Manfred of murdering his sister-in-law's embassador – it may be observed that, tacitly, he acquits him of parricide, fratricide, and nepoticide – requires a little explanation.

[Charles] Dickens did not get to work out the interplay between these varying guardians and their various wards; and if the murder was to be a nepoticide, it remains forever shrouded by non-completion.

The idea of parricide should be defined elastically enough not only to include avunculicide but to make it optional whether the youth or his father takes the initiative in expressing the antagonism between them. In the story from New Guinea, there is sexual jealousy between a father and son, and the father eventually kills the son instead of the other way around. In the Trukese story, we have an attempt at nepoticide, for the uncle tries to kill his nephew.

Quotations
The fact that the Yongle emperor was therefore a usurper, regicide and nepoticide (nephew-killer) made compiling the Veritable Record – or official history – of his reign a most dangerous scholarly post. The official given this ticklish task managed to survive several drafts, finally producing one that pleased his master as it omitted the dead nephew's reign altogether.
