He didn’t believe Christa Peterson when she declared that she was willing to meet him for a sexual rendezvous. In order to ensure that their liaison actually happened, he withheld the name of Professor Emerson’s Canadian fidanzata on condition that Christa meet him in Madrid in February. Christa was unwilling to wait that long or to sleep with him again in order to ferret out the information, so she didn’t respond to his last email. She decided to regroup and find an alternative way of discovering the name of Professor Emerson’s fiancée. It could be said that she was jealous and that this was her primary reason for wondering who had successfully captured the Professor’s attention when she had failed (inexplicably). It could be said that she’d begun to nurse a suspicion about a certain doe-eyed brunette, ever since Professor Emerson had almost come to blows with that student over a mistress called Paulina. But perhaps the most accurate explanation was her new and rather prurient fascination with the rumors she’d heard about Professor Singer and her not-so-secret lifestyle.
