"'Darling,' she said. 'Would you like me to get you some cheese? I haven’t made any supper because it’s Thursday.'"
"'I’ll get the supper,' she managed to whisper, and this time he didn’t stop her."
This proves that she was loyal and true to her husband when she was standing outside waiting for his return.
"'Patrick’s decided he’s tired and doesn’t want to eat out tonight,' she told him. 'We usually go out Thursdays, you know, and now he’s caught me without any vegetables in the house.'”
In this picture, we see that her husband is having a serious talk with her. She is disappointed with her husband.
"'Quick! Come quick! Patrick’s dead!' 'Who’s speaking?' 'Mrs. Maloney. Mrs. Patrick Maloney.' 'You mean Patrick Maloney’s dead?' 'I think so,' she sobbed. 'He’s lying on the floor and I think he’s dead.'"
This proves hat Mary Maloney killed her husband after when he told her the news. She was upset at him for whatever reason.
'"You must be terrible hungry by now because it’s long past your suppertime, and I know Patrick would never forgive me, God bless his soul, if I allowed you to remain in his house without offering you decent hospitality. Why don’t you eat up that lamb that’s in the oven? It’ll be cooked just right by now.'"
She went to the store while acting like her husband was still alive. She had a very nice conversation with the cashier. She got some food for her "alive and well" husband.
This proves that she was only trying to act like she was ok. She was "shocked and heartbroken" when she came home to find her husband lying on the floor.
She called the police and they came as soon as they could. She offered them some of the lamb leg that she still had inside the oven. They all agreed to have some food before they continued to look for the weapon and murderer. As you can see in the picture, she is in the back with a grim face and how she succeeded is a mystery.
