Perhaps no Prince of Wales in history has been less trusted — or more spied upon — than the boy everyone knew as Bertie.

He even had to share a general’s quarters. Happily, however, they had not thought to lock Bertie’s bedroom window. So, one night, the heir to the throne wriggled out, made a beeline for the camp prostitute — one Nellie Clifden — and triumphantly lost his virginity.
