He was very happy after this discovery. He felt bliss and relief. He slept whole night again after many days, even with the burden of murder upon his soul.
The fourth day after murder a party of the police came over unexpectedly into the house, and proceeded to make investigation of the premises. He knew that his nest is inscrutable. He felt no embarrassment. The officers bade him to accompany them in their search. They were three or four times in cellar. They didn’t find anything. As they were leaving, he didn’t control himself in the feeling of absolute triumph and wanted to say something triumphal and something what would doubly sure their assurance of his guiltlessness. He said that he is glad that he had allayed their suspicions. He said that he has very well constructed house. Then, with a cane, he knocked right at the wall, where the corpse of his wife lied. Just with reverberation of his blows he was answered by a voice from the tomb. It was a cry, at first muffled and broken, like the sobbing of a child, and then quickly swelling into one long, loud and continuous scream, utterly anomalous and inhuman.
The man was shocked. The policemen dismantled the wall in a moment and found the corpse. There was the cat sitting on the head of the body.
