is gone, Iris realises that the scratch marks on the inside of the ring are actually encoded data giving a GPS location. She rushes out of the hospital to investigate. The coordinate turns out to be the location of the ruined Tyrell building (destroyed in The Edge of Human). Iris is surprised to meet Vogel there. Vogel takes Iris into the ruins of the Tyrell building to show her where the owl came from, and talks about Tyrell's history, including the death of Tyrell at the hands of Roy Batty. Iris has not heard of this murder, and Vogel is surprised, and uses a video projector in the quarters to show her the movie Blade Runner (which, within the book's setting, is a documentary). Vogel then points out something that Iris herself had not noticed: that the Rachael replicant looks identical to Iris. In the monitoring suite, the director comments that Vogel was not supposed to say that, and the camera operator asks why Iris would not have spotted it for herself. As Iris and Vogel are in Tyrell's quarters, they hear someone else trying to break in. Vogel says that he has "gone off-script", and that the people coming are probably the film crew. Iris and Vogel escape through a tunnel in the ruins, but Iris is quickly captured by a fleet of spinners and taken to a distant location in the desert. In the desert base, Iris asks if she will be allowed to meet the director, but the guard claims never to have heard of him, and then leads Iris to meet an elderly man called Carsten. He explains that their group is an alliance of former technical staff from other replicant companies. Tyrell did not invent the replicant process; the UN destroyed the other replicant manufacturers in order to artificially create Tyrell's monopoly, using Tyrell just as a pawn. Carsten takes Iris into a frozen duplicate of one of the Tyrell labs - Chew's eye lab. He explains that Voight-Kampff machines did not really scan people's eyes and breathing to determine if they were replicants or not; the machines were searching for something else, and even contained lethal booby-traps to catch those who attempted to dismantle them to find out what it was. Carsten then shows her that the lab also contains a number of replicant duplicates of Eldon Tyrell. Iris is unimpressed. Carsten explains that
