Stalked by fear amid the shadows of midcentury Boston, the young divorcee from the projects harbors a deadly secret about her Brahmin boss. When security guards fail to protect her, we are led on a thrilling romp from a stodgy early mutual fund start-up, through pulsating Cuba at the dawn of the revolution. Half a century later, her grown-up office boy completes the jig-saw puzzle. This sequel to "South Boston Boy" is inspired by true events.
