The story itself is pretty decent, but on principle, I have to give this story a 1/10 for being overtly transphobic for no reason whatsoever.
This, for me, is one of the case studies as to how bigotry affects your reasoning skills, because the transphobic writer of this story made Captain Jack Harkness of all people, the openly omnisexual man from the 51st century, have a problem with trans people. Not the rapist. Not the police officer. Not the slightly withdrawn, quite traditional woman. Captain Jack Harkness, which on its own doesn't pass the smell test, but then puts it down to him not being able to trust his friend because she realized something about herself???
Ridiculous, callous, horrible, terrible.

1/10.
