Peter Straub's Mr. X is an enthralling, complex tale of a decent young man troubled since childhood by barely understood flashes of precognition and an awareness of a shadowy "other." Ned Dunstan returns home to Edgerton, Illinois, a raffish and atmospheric Mississippi River city, as his mother, Star Dunstan, lies dying. Impelled to trace his tangled paternal lineage after Star's death, Ned finds himself caught up in a web of murder and other heinous crimes, not only in the present but also in a past that his elderly great aunts Nettie, May, and Joy would prefer remained undisturbed. The aunts, whose remarkable gifts include teleportation and telekinesis, frustrate his search for knowledge, partly to protect their own secrets and also to shield Ned from the mysterious and omnipresent force that seems to dodge his every step. He is aided in his efforts to discover the mysteries of his birth by a doppleganger who may or may not be his twin, and also by a lovely young woman, Laurie Hatch. She is the estranged wife of Stewart Hatch, an Edgerton scion whose own history is inexorably linked with Ned's and with the entire Dunstan family.
