Now, That's a Good Question! by R.C. Sproul (Tyndale) & Free Fall by William Golding (Penguin). Happily, I noticed last night that my copy of Free Fall once belonged to the late, great Milton scholar (and Member of the Order of Canada, Order of the British Empire, and so on) Ernest Sirluck. ('Ernest Sirluck' is embossed on the upper right corner of the title page; and I purchased the book [randomly, for a couple bucks] at a book sale of the University of Toronto, where Sirluck was Vice-President in the 60's.) I love stuff like that.
