All meals Tom shared with Verna were either pre-packed or had been delivered. He did not eat her cooking.
When their first child was born, Tom changed his working hours from 8:30 to 4:30 to 10:00 to 6:00.
He would rise at 8:00 take care of the baby, prepare his own breakfast and a carry away lunch, letting Verna sleep. Leaving early he gave himself time to relax. After work Tom would eat out or at a friend’s house, and arrive home at about 8:00 p.m.
In this way, he avoided Verna, her cooking, the baby.
Verna thought he worked so hard and was exhausted when he entered, which is why he usually went straight to bed.
Tom was a master of this kind of misdirection.
