MixedThe Telegraph (UK)\"Doppelganger is a weird book. How could it be anything else? It is a deposition filed to prove that the author is not the same person as her subject. It is a horror story that describes how it feels to have your public identity intruded upon, cuckoo-like, by a monstrous rival. It is an attempt to understand the popularity of the conspiracy circus in which Wolf is now a leading performer ... Klein’s relationship with Wolf gave her the mirror as an instrument to analyse conspiracy culture. I’m not sure the rest of us need it. We might simply think of Wolf’s work as a bad habit that flourishes in media spaces where standards are sufficiently low to permit it: Steve Bannon’s War Room, for instance, or (to pick an example closer to home) GB News, which was happy to broadcast Wolf’s falsehoods about the vaccine, unopposed, until Ofcom intervened. But Klein needs the mirror because, ultimately, Doppelganger is about her.\
