The Eye of the Kaleidoscope

Dearest Dr. __________.   I'm in danger. I don't know if they're listening or not, but I know I'm not alone. They're close now. Closer than they should be. I shouldn't have done this. I shouldn't have gone out there...   Please, doctor. I need you urgently. You'll find a ticket to New Orleans in the envelope as well as directions to my apartment. Please hurry. We may already be to late.   Yours,   Gerald Ward
