Strange Story by Hilda Lewis. 
'LYING THERE. . . with her miraculous twins. . . Emmy Wilder was the happiest woman in the world. It was well that she was not to know that she held in her arms the killer and the slain. . . .
This is the story of twins, who develop differently-Lily, pretty, slovenly, with easy shallow affection;
Rose, determined, narrowly but deeply affectionate. Both girls are affected by the peculiar bond of twinship-Rose passionately possesive, Lily, in revolt, desperate to escape. Their lives lead ever apart: for Lily, marriage and children; for Rose, a career.
Then—the result of long suppressed affection and revolt-the quarrel.
A hand raised in anger. Death by accident.
What must the killer do? She is spiritually innocent. She has deep responsibilities; she must protect herself. She has the right to protect herself. And Fate finds a victim.
Now follows the long torment of her spiritual agony. She must escape but can she let an innocent man hang? Haunted, remorseful, resentful, she works out her problem.
