A strange sight greets Chicago haberdashery clerk Rufus Ker as he prepares to begin his workday by unlocking the door to Bluefield, Inc. A sign is attached to the glass. It reads: DEAD MAN INSIDE! I AM DEAD. THIS STORE WILL NOT OPEN TO-DAY.

Once inside, Rufus is relieved to discover the shop is still in one piece and assumes the sign to be a prank. But no one is laughing when Rufus realizes the dummy in the window is no dummy at all. It's the body of his boss, Amos Bluefield, and unfortunately this is only the beginning....

Scientist, explorer, and former intelligence officer Walter Ghost has come to Chicago to research some history, but after a stint in the hospital due to appendicitis, he quickly finds himself investigating a string of puzzling murders. Ghost is certainly no stranger to playing detective, but if he's not careful, he's about to get more familiar with the hospital.
