I think I have them all.
1-9, then 16 and 17. Numbers 10-15 were James Bond, I think. I loved these books when I was a teen. I wish they were still published with the original covers. My copies are pretty worn out, since I got them as they were published. I think a couple were reprinted to cash in on R.L. Stine's name after the Goosebumps series became popular.
