 Late one night, a man (seen only from the shoulders down or in silhouette) enters the Dodge House Hotel, swipes a room key, lets himself into the room and goes back to return the key. A few minutes later, the room s occupant comes in. As he shuts the door, he looks up and sees the silhouette -- pointing a rifle at him. The slug drills him through the heart, but there is no sound of the shot and he s not discovered until the next morning. Newly thinks that someone could fashion a device to silence muzzle blasts. Matt sends word throughout Dodge and the nearby communities to form a street police force. But the killer strikes again the next night, and the next. Matt s now convinced that the serial killer is choosing his victims for a specific purpose -- most likely because they served on a jury. Matt questions Doc, who s lived in Dodge the longest, about the juries he remembers serving on and whether he remembered the men who served with them and who they judged. From Doc s information, Matt figures that Doc himself is the next on the list. But when the chief suspect is reported already dead, Matt must try to find the killer all over again.
