Near the start of Edgar-finalist Gardiner's solid follow-up to The Dirty Secrets Club, San Francisco forensic psychiatrist Jo Beckett examines Ian Kanan, a distressed airline passenger who turns out to be suffering from anterograde amnesia, which makes it impossible for him to form new memories. Kanan, who's sure that his family has been kidnapped and he's been poisoned, disappears from the hospital before Beckett can learn more.
