Some years ago Little Joe, a young lowland gorilla, escaped from the Franklin Park Zoo. He was found at the bus stop near by and returned without incident. Why did he run? His niece Kambiri told me through sign language that he had seen a mysterious creature creeping through the tropical building. It stuck to the shadows, but he could see the long fangs and glowing eyes and feared for all the animals. Knowing that he was the only one both strong enough and light enough to break out, he climbed out of the gorilla enclosure and attacked the creature. It ran, but Joe smashed through the exterior door and chased it out of the zoo. All of the animals consider him a hero. To this day he has trouble sleeping and the keepers give him chamomile tea.
I think there's a flicker of betrayal in Jack's eyes!
