'Should I tell you that I have tried using the instructions on my own power?'
'No, I can not do that. It will mean that I have to tell the Duke that I can read minds.'

'Should I tell him that I have made Amy practice it over the years?'
'But Duke Salvador had seen it with his own eyes that I was teaching Amy for the first time.'

[I think he went here]
[Should I search in the old abandoned book area?]
[I think the Duke came here to search some ancient book that he is curious about]
