Five Fathoms of Pearls by James H. Beard (Unknown, December 1939) opens with Peter Hume staring at a wall in his house as if he can see something there. He subsequently goes out and rides through the wind and rain and dark to an inn, where he finds a cousin of his called Allen Dorn. Hume tells Dorn to return to the house with him, a property that was once owned by a witch, Elsie Dorn, a grandmother to both men.
Inside the house Dorn sees that the wall which Hume was staring at has a window which shows a sundial in the distance illuminated by moonlight—quite a different view from the other window in the room that shows the rain that they have just ridden through. While all this is unfolding we also learn about (a) a ship that the cousins pirated for gold and whose skipper they drowned, (b) a note from Grandmother Elsie about a chest at the foot of a sundial containing a string of pearls five fathoms long, and (c) instructions to look after a relative called Harriet Dorn, or suffer her vengeance (needless to say, neither of the men have done so).
The final part of the story sees the two climb through the window to get the chest but, during their journey, they see two dead girls from the ship pass by on a lane before seeing the cutlass wearing captain. The captain stares at the men but is scared off by the returning girls. By now the men have recovered the pearls and flee when the girls approach and touch them. Dorn falls but Hume makes it to the window. Then (spoiler), Dorn shoots Hume so he won’t be stranded outside the window. When Dorn reaches the window Hume uses his remaining strength to stab him.
There are too many moving parts here for such a short story (the pirating of the ship, the supernatural window, Harriet Dorn, etc.), and the ending is too abrupt. I’d also add that the men’s downfall is down to their own distrust and has little to do with the vengeful dead grandmother.
