So the good news is that I'm good at imitating P. G. Wodehouse and Arthur Conan Doyle when I try to. The bad news is that apparently, much of the rest of the time...
I write like
Stephen King
I Write Like by Mémoires,
Mac journal software.
Analyze your writing! I haven't read a whole lot of King, but I bet it has a lot to do with my (very liberal) use of dialogue. Also, my Jules Verne fanfic came up Dan Brown, for some reason--lots of exposition?
Anyway,
this thing is kind of entertaining.
