What happened to that detective was genuinely disturbing.
And to be pregnant too.
My theory at the start was that someone entered her apartment after Andrew left and raped her. The ex boyfriend or the chatty cab driver.
Then it switched to the detective woman's partner. That actor is too well known to take a meaningless role as a sidekick with so little screen time. So I'm still expecting some 11th hour twist where he helps Andrew to cover his tracks, or it turns out he was the one to rape his partner and not Andrew at all.
