Meet Edward Rollins, scion of one of Boston's more notable families. A diligent but uninspired employee at one of the city's finest investment houses, he is a man of means -- and of secrets. Each night, armed with a hand-held tape recorder, he randomly picks a car and follows it to a destination, cataloging the habits and peculiarities of its driver. A harmless obsession. But one night changes everything. Trailing a car to a remote suburb, Rollins follows it to a house that, he eerily realizes, was once frequented by his murdered cousin. Drawn into a mystery to which he unwittingly holds the key, he must unlock the secrets of his past to find the truth -- a search that could free him from his own dark house of despair.
