You could always "Come Clean" and admit what you want to learn. You might find more useful specific advice for your instrument. Many 'catters can give advice about tutorial books for a particular instrument or style of playing.
Just an afterthought!

p.s. I myself am starting to mess around with a fiddle - my agenda is American Old-Timey tunes rather than any other style. I already play mandoline, so DO know the fingerings and just need to turn them a different direction. Any good advice folks!
