A ghost has invaded his home, beginning a dangerous nightly game in which Henry is allowed to ask a single question. If the answer is no, an innocent and unsuspecting person is killed. Henry soon comes to the horrifying realization that this wraith—and the others who join it—is using him to wreak vengeance on the people it holds responsible for its death. Henry can't find the source of these murders on his own, so he calls on the one person he trusts to help—private investigator Vicki Nelson, with the small hope that they can stop these otherworldly forces, without losing their lives. Also includes a brand-new short story featuring Vicki and Henry!
