One night when he's out drinking, another black cat appears on the scene. This cat looks just like Pluto, except for the little white spot on his chest. The man takes the cat home, and his wife is quite pleased.
When it is discovered that this cat is also missing an eye, the man begins to despise it. The woman shows the man that the white spot on the cat's fur has grown. Oddly, the white spot now forms an image of "the GALLOWS!"
One day he and his wife go down to the cellar of the old house they live in now that they are poor. The cat follow them, the man tries to kill the cat with an axe. The woman stops him, and the man hits her with the axe, killing her.
The narrator wonders how best to conceal the body? The man decides to hide the body in a space behind the cellar wall. That night, the man sleeps peacefully for the first time in ages. The cat is nowhere to be seen. The police visits him but find nothing
He brags about how his house is well built and hits the wall with the cane. A noise answers his knock! It sounds horrible and desperate, but also victorious. The police open the wall finding his wife body and a black cat accidentally buried behind the wall as well.
