What is the grammar behind いないてえ?


This is a sentence from a tale I'm having trouble with. It is a Tengu speaking
to a boy:

> まったくおれは何の術もかけて **いないてえ** のに本気にしやがって。

I understand this sentence to mean something like 'To be honest I haven't
actually granted you any skills.'

What does いないてえ stand for； what kind of verb form is this (if I am right to
assume it is some negative form of the verb いる）?




This sentence is perfectly Edo dialect. いないてえのに accurately means いないっていうのに or
いないというのに (いない-と-いう-のに) in normal Standard language.
