Capital letter in ( ) is a title, others are names
1. C. washing aid with changed cave
2. (M) guillotine observer
3. W. Lily the Pink character
4. A. shortened journal with evil woman
Just as an aside, it was only fairly recently that I learnt that Lily The Pink was a real person (Google Lilian Pinkerton). The reason her medicinal compound was 'so efficaceous' was that it was 15% proof alcohol!
