Martha Ferris didn’t see herself as a bad person, never went out of her way to hurt anyone. She just made a point of looking out for number one and if that meant trampling on other people, too bad.

When money was tight, she had a trick to save on food bills. Namely pinching grub from the fridge at work. Taking pride in her quick sleight of hand, as she grabbed her can of coke, she’d shove Rachel’s mini sausages or Nigel’s rice balls into her handbag, but it was Holly Blackbone she loved to steal from.
