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.
