Held By the Hitman by Diana Bell

I know she’s lying about who she is.
After I brought her home last night, she’s still here the next day. I’m in no rush for her to leave, either.
But she’s looking for something, I can tell.
I may not know the exact truth, but here’s what I do know: She’s mine.
She was mine the moment I laid eyes on her.
But in order to get to the bottom of this plan, I need patience.
So, patience it is.
Who can wait this out the longest?
At least I’ll have some fun while we see how long this lasts.
