Communicating Doors

The communicating doors of the title are in a hotel room and they, to the guests' surprise, allow some of them to travel through time, returning to the same hotel room. But not everybody gets transported to the same era! Julian has procured a prostitute for Reece. As it turns out, Reece doesn't want her for what she usually gets paid for, but instead wants her as an independent witness to a confession and then deliver it to trusted hands. Reece has been very successful in life, along with his business partner Julian, but it has come at a high cost. Two of Reece's wives were killed along the way. The killer gets wise to the fact that there is a confession revealing his crimes and that the girl knows about them and, naturally, he plans to get rid of her as well. She escapes, sort of, through the infamous communicating doors. Can she convince Reece's wives that they are in danger? Or will the killer find her first?
