With a brilliant smile, Sherlock kissed Janine, and then disappeared down the stairs. Still mystified, John asked, "So, obviously I know how you two met, but, if you don't mind my asking …"

"What made us interested in seeing each other afterward?" Janine asked, in her flippant but surprisingly astute way. He nodded, watching her from under his eyebrows and over the edge of his mug of tea.

She laughed. "We do have something in common, you know, besides a mutual interest in … experiments." She inclined her head toward the bedroom with a sly smile, and John blushed violently. Relenting, she said matter-of-factly, "I know you don't think I'm in his league on any level, but he and I studied the same thing at Cambridge."

John reflected that he'd just learned a lot from that simple sentence. Perhaps he could learn more.

"Chemistry? Biology?" he ventured, but Janine was shaking her head. "Criminology? Law?" Now she was smiling broadly.

"You really don't know, do you?" she chuckled, rising from her seat and striking a dramatic pose. Wearing only one of Sherlock's dress shirts, she had John's full, if somewhat guilty, attention. "Although I later went into business, and he went into detective work, originally, we were both there on scholarship" – here she executed a neat, graceful pirouette - "for ballet."
