I've got two answers:
1. I'm waiting ever-so-impatiently for Amazon to deliver my latest order which contains Dorothy L Sayer's translation of Dante's Inferno (in three separate books: Hell, Purgatory, and Paradise). I've been wanting these books for a looooooong time. They could come any minute now and I wouldn't complain.
2. The last two entries in the Philo Vance Series by S. S. Van Dine (The Garden Murder Case and The Winter Murder Case). Getting my hands on these would be both good and bad. Good because I would finally have and be able to read these; Bad because I would then have finished the series and there would be no more Philo Vances to read.
