There's a photo of Andrew, Epstein and Maxwell supposedly at Balmoral. It shows the three in a field talking.
i don't mean to make light of this by any means, this happened in 1999 before the true nature of Epstein's doings came to light. There were stories/rumors going on the down low, but they were looked at as just rumors.
We'll find out especially if some staff do report that they had suspicions at the time, but due to the job, had to remain silent or were afraid to speak out.
