Paul gave me a copy of your Kuttner Want List (as of 12/7/87) and I think I may have found something for you! I recently acquired a copy of "Clash by Night" under the pseudonym Lawrence O'Donnell. The story appears in The Astounding Science Fiction Anthology edited by John Campbell, Simon and Schuster 1952. It's an excellent piece of work and was unlike any Kuttner story I've read before. If you haven't already acquired it yourself, I'd be glad to send a photocopy.

Incidentally, you might want to send us a copy of your want list. You could organize it nicely as a HyperEssay using HECK/ASK, but sending a MacWrite (or text) file will work just as well.
