I have started re-reading Ngaio Marsh's delightful detective novels featuring Roderick Alleyn. Here are the publications mentioned in the first two:
- Suspense - Joseph Conrad
- The Kreuzer Sonata - probably the novella by Leo Tolstoy, since the owner of the book is Russian
- Webster‘s Dictionary
- Eyes and No Eyes - There are several publications with this title and I can't begin to guess which one is being referred to, because the reference completely went over my head.
- The Ideal Home - this appears to be a magazine along the lines of Better Homes and Gardens.
#2: Enter a Murderer:
- The Rat and the Beaver - an imaginary play by an author whose name is not given; the murder takes place on stage during a performance of it
- The Pirates of Penzance - comic opera by Gilbert & Sullivan
- Othello - Shakespeare
- Madame X - Alexandre Bisson
- The Morning Express - newspaper, may have existed at that time but no longer
- La Vie Parisienne - French erotic magazine (typically, the evil murder victim has a 'striking' framed picture from it hanging in his apartment)
