When I finally reached the table, Mr Amos was looking embarrassed, as if he didn't want to be seen with me. I could see he was trying to hide it but he couldn't. Suddenly a strange thing happened: he opened his mouth, as if he was going to speak, then stopped. He had smelled the perfume - the fruit cake special - that I was wearing, and the change that came over him was immediate. His look of embarrassment just disappeared. Instead, he looked like a dog who had just found a bone; his eyes shone and he smiled until I thought his face would break in two. He stood up.
