"Who are they, the strangers you pass, the strangers who pass you, at the supermarket, at the mall, on the road? Take that dark Nissan in your rearview mirror. Just another pair of headlights on your stretch of highway, you think." "You adjust your mirror." "He's still there - a lone male, late thirties. Rather handsome, actually. And his eyes are on you. And they stay on you ...".

"Meet Edward Rollins, scion of one of Boston's more notable families. Securely yet unhappily employed at one of the city's finest investment houses, he is a man of means - and of secrets. What began as a lark, a way of unwinding, has become for Rollins an obsession. 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, imagining from those details the sort of life that might have been his.".

"But one night changes everything. Trailing a car to a remote suburb, Rollins follows it to a darkened house - and into a terrifying, decade-old mystery."--BOOK JACKET.
