When a mild-mannered IT specialist discovers that a man with the same name as his is missing, he goes looking for him in the Toronto ravines. But instead of finding him, he finds the missing man's identical twin brother.
Carl Naardlinger has spent most of his life answering questions. When your computer doesn't work - he is the man you call. Patient, intelligent and kind he is a voice in the interconnected ether - touching the lives of thousands of people he will never see, or meet. When he discovers on his birthday, that a man with the same name as his has gone missing and is presumed dead - Carl instinctively feels related to the stranger that bears his own name. Pam, his wife, is unnerved by a shocking coincidence of her own, when their annoying neighbour dies after she wishes it. It seems the Universe is playing a cruel joke on them both. Things get stranger when instead of finding the missing Carl Naardlinger, Carl finds his identical twin brother Don who happens to be in town for a conference.
