The Game You Played — Anni Taylor

Little Boy Blue, where did you go?  Who led you away?  Only I know . . . .

Two-year-old Tommy Basko vanishes from a popular inner-city playground. Six months later, his parents begin receiving cryptic messages in rhyme about Tommy. 

Tommy's mother Phoebe is certain the letters are from the abductor. Someone is taunting her. But who?

Phoebe begins a frantic search for the writer of the rhymes, against the advice of the police and at the cost of causing her marriage to shatter. When the shocking identity of the message-writer is discovered, more questions are raised than answered. Phoebe's desperate race for the truth has only just begun.

Who took Tommy?
