When I review the series now, I amuse myself with answering questions like "what if all of the odd behavior of the town's residents like Audrey's itchy palms or Harold's agorophobia are really drug side effects?" or "What's with all the shoes?". Shoes that are sold by a one-armed former pharmaceutical salesman. Could cost-effective, comfy, industrial footwear have been used as a delivery system for a gateway drug through absorption (a TORB word) through the soles of one's sweaty feet?
TORB of course were the four letters found under the nails of the Killer BOB victims. BOB said that he was spelling out Robert but can we really trust BOB? Dwarf spoken backwards can be pronounced Fraud, after all.
