The difference between the show and the story of The Lamb to The Slaughter

The 2 main characters in this story is Mr. and Mrs Maloney.In the end, Mrs Maloney murderred her husband as he was going to divorce her even when she was pregnant. Resulting in, Mrs Maloney to be furrious so she took the lamb(frozen leg)and smashed him in the back of the head.Owwww!......Causing him to die.
In this post I am going to tell the difference between the two visual and written source.
Here
-Mrs Maloney did not rehearse her speech
-the freezer was in the garage instead of the cellar
-The investigators/police took coffee instead of wine
-Mrs Maloney did not sew while waiting for her husband to return from work.
-In the written story she did not mess up the place
-In the show Mr M. told Mrs M. that he wanted to divorce
In the show the police was more specific
