Valerie Bland in “Unfinished Business”

[after Poirot exposes her and her accomplices] Kathy said she knew how to make it work, that there was a young tart at the bureau who no one would miss, who would deserve it. She said she'd set her up, it would be all right. They said there would be no reason for the body to be at the blind woman's house with Sheila Webb and it would just confuse the police. It would be confusion upon confusion, complication upon complication. Joe worked so hard all his life for nothing, and the money was so huge. It, it was so huge! But they made me do it. They, they made me put the knife into Sheila Webb's bag at the inquest. They made me press Merlina to come and lie, to falsify the marriage and falsely identify the body. And, and, and then, when she was scared, to, to come to the seafront so they could kill her! It was only going to be the one death. It was only going to be the one!
