By the time I got home, I found a message on my machine from one Beryl Hollyburn, Dr. Skyhill's executive assistant, confirming that I and my guest had an appointment at ISP the next day-that is, today-at eleven. I immediately called Jocasta. Barnard was right that I'd need someone along who could ask intelligent questions and understand the answers. Jocasta's field wasn't specifically biotech or bioengineering, but she was closer to the mark than I was. Besides, I didn't want to drag someone else in to this.
