Bony

Bony -- properly speaking, Detective Inspector Napoleon Bonaparte -- is the protagonist of a long-running Australian series of detective novels by Arthur Upfield. The first novel of the series, The Barakee Mystery, was published in 1929, and sequels continued to appear until the author's death in the 1960s.

A university-educated police officer, Bony is half-Aboriginal but was orphaned at a very early age and raised in the white man's society. He got his name at the orphanage after being found teething on a volume of Napoleon Bonaparte's memoirs. He is also familiar with Aboriginal culture, which often proves useful, and frequently works undercover, using his half-caste heritage to disguise his intelligence and education.

The novels were adapted for radio early on, and for television in the 1970s under the title Boney. In the 1990s, there was a TV series called Bony starring Cameron Daddo as Detective David Bonaparte, supposedly a descendent of the novels' Bony.

Tropes used in Bony include:

The novels provide examples of:

Blue Eyes: Bony has them.
Halfbreed: Bony is one of the fortunate examples.
Scarily Competent Tracker: Bony has his moments.
Write Who You Know: Bony is based partly on a half-aboriginal tracker the author had met.

The adaptations provide examples of:

Ascended Extra: Constable McGorr only appeared in one novel, Murder Must Wait, but was made a regular character in the 1970s series so that Bony would have somebody to explain his thought processes to.
Everybody Is Single: In the novels, Bony is middle-aged and married; in the 1970s TV series, he's twenty years younger and single.
Fake Mixed Race: Radio series -- fully white actor. 1970s TV series -- fully white actor, and not even an Australian. 1990s TV series -- fully white actor.
Setting Update: The 1970s TV series was set in the 1970s.
Spin Offspring: The 1990s TV series.
The Watson: Constable McGorr in the 1970s series.
