Taking time away from his quest from publishing a great novel, Lum puts the printing press to work with a job that actually makes a little money. He and Abner talk about a recent rash of robberies, and worry that their money will be safe until they can pay their bills at the wholesale company. Suddenly their front door bell rings, and an intruder enters. Is it the robber? Are they going to be safe? Nothing is taken, but a package is left.
It’s a manuscript from a phantom author. It’s a curious situation, but the mystery story gets hold of Lum, and draws him into it. Has he found his first author that wilkl put his publishing house on the map? The tale is one full of chills, and thrills, and things that go bump in the night. Abner is soon fearful of every sound in the store as they read the manuscript through the late hours of the evening. Maybe it’s all just a ruse to let the robber sneak in to do his dastardly deeds.
