The Rottweiler, by Ruth Rendell

We don't get to watch many of these characters eat. It is a cast of many, but the ones who seem to eat most often are Becky and her nephew Will.

Will appears to subsist on eggs, toast, fried potatoes (chips), sometimes fried tomatoes. He brings sandwiches for lunch with the ingredients not divulged.

Becky too offers and eats eggs for dinner from time to time, more often than I'd expect. She prepares a meal of porked chops, mashed potatoes, peas and carrots for Will and his "girlfriend" Kim.

Kim and Will go out to eat at a Lebanese restaurant one time, but we don't know what they had.
