Check this quote out from the play,

"Who did this, Mrs. Wright?" said Harry. He said it business-like -- and she stopped pleatin' of her apron. "I don't know," she says. "You don't know?" says Harry. "No," says she. "Weren't you sleepin' in the bed with him?" says Harry. "Yes," says she, "but I was on the inside." "Somebody slipped a rope round his neck and strangled him and you didn't wake up?" says Harry. "I didn't wake up," she said after him.
