It's a rainy Wednesday afternoon. Pat closes the office early and goes to the barber's. Whilst having a shave he is approached by a stranger who wants to hire him to follow a woman, Agnes Bolton. He will find her at the bowling alley at 7pm. She will pick up a green leather bag and then head down to the harbor to her boat "Seventh Heaven". Pat is paid to follow her and get the name of the boat that she drops the bag with. But he is not the only one after the green bag.
