A sense of 'what the heck'???

I have two stories being written//edited that are a bit more macabre than my normal fare.
Ok, so on is where the hero/heroine is being stalked and the other is where they are involved with solving the crimes.
The latter one I strted writing in 2013 and is at least 6 parts. The former is something I wrote on a recent flight from Dubai to London.

Then I pick up a book called 'Deja Dead' that features Temperance "Bones" Brennan.

IT features stalking and other nasty stuff that make me so WTF? There are plots/subplots that seem mightily familiar to my stories. There is no way I got the ideas for my stories from that book but ... well ,you never know.

Now my dilemma. Do I post my work and get called out for plagurism even though I never read the 'Bones' story until most of mine were done or do I put them in the file called 'Do not publish' or do I change them so that no one could accuse me of copying another persons work.

Well what do you think?
