Moebius Chapter 1

Hi. I am stuck on chapter one. How do I buy the necklace in the antique shop in Venice? In my inventory I have the passport, wallet, 2 lots of pills and an object I think is a pole and my phone. I know there is an object in the canal and I have spoken to the lady who owns the house next to the canal. I have visited the murder victims house and spoken to her husband and explored her room. Not sure what to do next. Any help is appreciated.

Have you talked to the old lady already?
Do a web search on the old lady. You will see the reason why you need the necklace.

Thank you I hadn't done the web search. That is what I was missing

Have fun now.
