"On the scent"

What's the meaning of that phrase? Context available upon request.

'on the scent'

means 'on the right track'

Imagine that you are a Private Detective trying to catch a criminal. If you spot a clue, then you are 'on the scent'. If you are 'clueless', then you have no idea who the criminal is.

The same applies with any investigation.
