can't find your my cousin
is matthew vett the main character or the author - there is no author listing for the name, which is why i ask.
This probably won't help you get much further, but https://www.fictionpress.com/u/912282/MatthewVett is clearly the same person. It looks to be his real name as well, which is probably why he deleted/renamed his profile.
Here he is again: https://matthewvett.wordpress.com/2012/annual-report/ and those "top 5" links all point to deleted content. Now you see him, now you don't.
