If clothes made a statement about the outcome of their wee-hours discord, Sam had clearly emerged the winner: dapper as always in a trim sports jacket, with his bow tie cleverly complementing the forest green highlights in his tweed trousers. Frances, on the other hand, was dowdiness incarnate in a drab, too-large tunic and a matching too-large pair of trousers. She looked like a refugee from the Cultural Revolution.

Polly seemed eager to mend whatever breach she might have caused between the professor and his wife. After all, she was nearly fifty years Sam's junior and a girl with a boyfriend back home in Chicago to boot. She might have enjoyed the attentions of an older man-a really older man, as she would have put it- in the college pub for several nights running, but that was not to say that she would ever have considered fanning the flames of Sam's interest to build to something more. True, he was extremely nice looking with all that gray hair and that blush of good health on his cheeks. But there was no way around the fact that he was also old, and he couldn't compare to Polly's own David despite David's so far unshakable and somewhat obsessive interest in developing a career studying howler monkeys.

Polly called out a cheerful good morning to the Clearys and motioned to them with her camera. She'd put on an enormous telephoto lens for their outing, which served her purposes well at the moment. She could take the picture she wanted of Sam and his wife while keeping her distance from them. She said, “Stay right there by the herbaceous border. The colours are sensational with your hair, Frances.”

Frances's hair was gray. Not that stunning white that some women are blessed with but battleship gray. She had a lot of it, which was fortunate, but the dullness of its colour made her look dour at even her best moments. And this not being one of her best moments, she looked pretty much the worse for wear.
