Which of these is the odd one out? Thanks in advance.

Treasure Island
The Prime of Miss Jean Brodie
The Picture of Dorian Gray

The Prime of Miss Jean Brodie is the only one written by a woman.

There may be several equally good answers for this.
The Prime of Miss Jean Brodie is the only one of the 5 written by a woman?

[Tilly2]

The Prime of Miss.....was written by a woman. The rest by men?

[fiction-factory]

Snap. Somehow though I doubt this is the answer the setter is looking for

Treasure Island ?? + Only one that doesn't have the as first word of the title

[Toorak]

They are all written by scottish authors except the picture of Dorian Gray

[fiction-factory]

The Prime of Miss Jean Brodie is the only title that ends in a vowel

[Kingpin4]

Dorian Gray seems the best bet it is the only one not written by a Scottish author.
