For this story, "Black Mask" had this to say: "One of our best detectives is this nameless sleuth of Mr. Hammett's. He's deductive, practical, and maybe a little unromantic. Probably that's why he runs into such wild adventures and takes such horrible chances. In this story he walks into a whirlwind of death. Got to it." The story is also known as "House Dick." The Op, who is never named, takes a three day security assignment at the Montgomery Hotel in San Francisco - the first two days go without incident. But, on the last day, he makes a gruesome discovery in room 906. It quickly gets complicated. At one point, we find our resourceful detective in a shoot out in a nearby bar with the most dangerous criminal on the west coast. Librarian's note #1: this entry is for the story, "Bodies Piled Up."
