The lives of two librarians become dangerously intertwined in this razor-sharp exploration of human nature and the lure of artistic obsession.

No one knows Margo’s real name. Her colleagues and patrons at a small-town public library know only her middle-aged normalcy, congeniality, and charm. They have no reason to suspect that she is, in fact, a former nurse with a trail of premature deaths in her wake. She has turned a new page, so to speak, and the library is her sanctuary, a place to quell old urges.

That is, at least, until Patricia, a recent graduate and failed novelist, joins the library staff. Patricia quickly notices Margo’s subtly sinister edge, and watches her carefully. When a tragic incident in the library bathroom gives her a hint of Margo’s mysterious past, Patricia can’t resist digging deeper—even as her new fixation becomes all-consuming and sends both women hurtling toward disaster.

Chilling, incisive, and darkly humorous, How Can I Help You is a propulsive work of psychological suspense that asks how far we might go to justify our most monstrous desires.
