Where do you get your ideas? The Noir Version

I am often asked, "Where do you get your ideas?" In some cases, that's code for, "Why don't you ever write "nice" stories?" (Those people should know by now that I don't do "nice" and they should  be glad. Writing dark fiction allows me to channel all the anger I feel toward stupid and cruel people and prevents me from being arrested for homicide, justifiable as it may be.) But I digress.
Like everyone else, I get the usual spam--for Canadian pharmacies, for penis extensions, for questionable legal transactions in Nigeria. These email missives go straight into my junk folder and are deleted en masse every morning.
But today I got an email that tickled that little spot on the back of my neck that tingles when the universe hands me an idea that might be a story if it percolates long enough.
It was from Marriedbutlonely.
Eeeeuuuuw.
The ads are aimed at guys, and promise that the women on offer are all "neglected housewives" looking for nothing more than a little fun.
Seriously, what could possibly go wrong?
There's a story here.
It's an old story for sure, but now with a technological twist.
