Please note imdb that this entry is a complete error!
There were only 12 episodes of 'Il Giovane Montalbano', in two series of six episodes each.
'Il Ladro Onesto' was in fact the penultimate episode, number 5 in series 2, and already appears as such in imdb. Not sure how it came to appear again in an 'unknown' series. Somebody there got it wrong!
The story of Young Montalbano very clearly concludes with "Un'albicocca". Series 2 episode 6.
I hope this gets read by a human, as computers don't seem able to work stuff like this out!
