Caught in Lies - Mahoney and Me Mystery Series, #3

A shot rings through the forest, and an old man falls. While on a bicycle ride, the narrator hears the blast from the gun, and the hunt for the murderer begins. Identity theft and impersonation lead Detective Mahoney and the narrator across the county to New York to uncover the connection between two 'look-alikes' who may be responsible for Homer Hunter's death. Or perhaps the answer lies in the boast of a disturbed youth who believes old people are useless and should die.
