The past 12 months have been a banner year for infidelity. Cast your mind back to last summer when the unfortunate tech CEO Andy Byron was snared in an intimate embrace at a Coldplay concert with a woman who was not his wife, but was, in fact, his co-worker. Then there was Olivia Nuzzi, whose bizarre decision to begin a romance with Robert F Kennedy Jr after profiling him for New York Magazine is relayed in American Canto, her memoir. This, in turn, has been extrapolated upon at tawdry length by her spurned ex-fiancé Ryan Lizza. (His Substack details the chillingly bad erotic poetry allegedly sent by RFK.)
