A competent, free-form little chiller that pedals you into the implausible before you can say "Cheese it! the Mafia!"--a Mafia whose sinister masterminds, along with the CIA, can fracture a young boy's life. Fourteen-year-old Adam is biking furiously from Massachusetts to Vermont to see his father. Yet distance and time seem oddly muddled as Adam's head buzzes with family memories and--like tape recordings--those interrogations by a doctor (?) about Adam's childhood. He can remember a time when he and his parents were happy and close, but, after that frantic exodus in the night, when Adam was a tot, things were never the same. It is not until Adam is a teen-ager that he discovers the reason for: Father's grim visitations from a "Mr. Grey," Mother's Thursday phone call, and his own double identity. The denouement seals the accelerating dread, with recollections of gentle domesticity and even some high school humor adding a mite more candle power to light this bike-ride through a twilight zone.
