Query: The story behind this book, well known in English History: hanky-panky.

John Dee, the man who invented the phrase 'The British Empire' had a pretty wife who was much younger than he.A much younger man, whose name I forget, helped him to write these books, then told him that the spirits-whom he had consulted- were suggesting that it would be a good idea if he slept with Dee's wife.Dee was taken in, and the man had his evil way with her.You should not take Dee's books unduly seriously.They are a con on many levels.Dee, after all, aimed to gain money and influence through them, as much as his helper planned to sleep with his wife.)
